Answer: 0.68 mole
Explanation:
1 mole (of any atom/molecule) = 6.02214076*10^23
0.683 moles are equal to 4.11x10²³ molecules of carbon dioxide.
What do you mean by the term mole?A mole is a unit of measurement in the International System of Units (SI) used to express an amount of a substance.
One mole is defined as the amount of a substance that contains as many elementary entities as there are atoms in 12 grams of pure carbon-12.
This number is known as Avogadro's number and is approximately 6.023 x 10²³.
Given:
For the number of moles of carbon dioxide in 4.11x10^23 molecules Avogadro's number = 6.023x10²³ particles per mole.
Therefore, the number of moles of carbon dioxide can be calculated as:
moles = number of particles / Avogadro's number
moles = 4.11x10²³ / 6.022x10²³
moles = 0.683 moles
Thus, 4.11x10²³ molecules of carbon dioxide are equal to 0.683 moles of carbon dioxide.

_______________________
The default constructor sets x and y to (0, 0) by calling the second constructor. What could be used to replace /* missing code */ so that this works as intended?
a = 0;
b = 0;
this (x, y);
this(0, 0);
x = a;
y = b;
a = x;
b = y;
_____________________
Which of the following correctly implements a mutator method for Point?
public double getX() {
return x;

public void setCoordinates (double a, double b) {
Point p = new Point(a,b);
}
b = 0;
this (x, y);
this(0, 0);
x = a;
y = b;
a =x
This above solution is just according to the public boolean equals(Point p) { return (x == p.x && y == p.y ); and public void equals(Point p) { System.out.println(x == p.x && y == p.y);}
What is public void?An abstract class contains a pure virtual function. Pure virtual class cannot be instantiated but it can be subclassed and the subclass can provide an implementation of the function.
A virtual function declaration in the class is preceded by the virtual keyword. For example, virtual void print();
A pure virtual function declaration is followed by '=0;'
public: virtual void print()=0;
The main method header is written as public static void main(String[] args). A main method is something that is required in Java. You must have at least one class with a method named main. In Java, main is a static method, which means that it is part of its class but not parts of objects.
Therefore, This above solution is just according to the public boolean equals(Point p) { return (x == p.x && y == p.y ); and public void equals(Point p) { System.out.println(x == p.x && y == p.y);}

How many hydrogen atoms are in the compound represented by the following bond-line drawing?
ОН
Answer:
Theres no drawing
Explanation:
Show drawing
Skeletal structural diagram and bond-line drawing are similar;
Parts of the question appear missing: The number of hydrogen atoms in the attached example bond-line drawing is 6 hydrogen atoms
The reason the above value is arrived at for the attached example bond-line diagram is as follows;
A bond-line drawing is the diagram showing the molecular structure of a compound, such that covalent bonds within the molecule are represented by lines with the number of lines indicating the number of covalent bonds.
A single covalent bond is represented by one line, double bonds by two lines while three parallel lines represents a triple bond.
In bond-line drawing, the lines symbolically infer the carbon to carbon bonds while the bonds to the hydrogen atoms are implied noting that each carbon has four covalent bonds. Hydrogen atoms attached to other heteroatoms are indicated with an H.
The number of hydrogen shown in the example diagram can be found by noting that the number of covalent bonds between the carbon atoms are three, therefore, the atom of the fourth bond not shown with a line is to a hydrogen atom
There are six such carbon atoms, one of which is attached to an oxygen atom, which gives five hydrogen atoms located on the ring
There is one more hydrogen atom attached to the oxygen in the hydroxyl group, the total number of hydrogen is therefore;
5 hydrogen on ring + One hydrogen in the hydroxyl group = 6 hydrogen atoms

In the 1860's the Central Pacific Railroad company employed the chemist James Howden to make an explosive capable of blasting through the granite mountains of the Sierras. The railroad needed tunnels for their train to pass through. James Howden built a nitroglycerin producing lab on Donner Pass where he would make the explosive compound on command. Nitroglycerin has the chemical formula C3H5N3O9. When it is detonated, it decomposes into carbon dioxide, water, oxygen and nitrogen. What is the theoretical yield for moles of nitrogen gas produced upon detonation of 1.320 tons of nitroglycerin? There are 907185 grams in 1 ton and nitroglycerin has a molar mass of 227 g/mol. Do not include decimals in your answer.
Answer:
8 × 10³ mol N₂
Explanation:
Step 1: Write the balanced equation
2 C₃H₅N₃O₉ ⇒ 6 CO₂ + 5 H₂O + 0.5 O₂ + 3 N₂
Step 2: Convert the mass of C₃H₅N₃O₉ from tons to grams
We will use the conversion factor 1 t = 907185 g.
1.320 t × 907185 g/1 t = 1.197 × 10⁶ g
Step 3: Calculate the moles corresponding to 1.197 × 10⁶ g of C₃H₅N₃O₉
The molar mass of C₃H₅N₃O₉ is 227 g/mol.
1.197 × 10⁶ g × 1 mol/227 g = 5.27 × 10³ mol
Step 4: Calculate the moles of N₂ formed from 5.27 × 10³ moles of C₃H₅N₃O₉
The molar ratio of C₃H₅N₃O₉ to N₂ is 2:3.
5.27 × 10³ mol C₃H₅N₃O₉ × 3 mol N₂/2 mol C₃H₅N₃O₉ = 7.91 × 10³ mol N₂ ≈ 8 × 10³ mol N₂

The total age of 5 children aged 3 years is 50 years. Find the age of the youngest and oldest child?
Answer: See explanation
Explanation:
Here's the correct question:
The total ages of 5 children born at the intervals of 3 years each is 50 years. Find the age of the youngest and the oldest child.
From the information given, we can then make the following assumption with regards to their ages.
First child = y
Second child = y + 3.
Third child = y + 6
Fourth child = y + 9
Fifth child = y + 12
Therefore, y + y+3 + y+6 + y+9 + y+12 = 50
5y + 30 = 50
5y = 50 - 30
5y = 20
y = 20/5
y = 4
Youngest child = 4 years
Oldest child = y + 12 = 4 + 12 = 16 years
Determine the mass (in g) of a substance, with a density of 2.26 g/mL, that occupies 350.0 mL.
Answer:
m = 79.1 grams
Explanation:
Given that,
Density, d = 2.26 g/mL
Volume occupies, V = 35 mL
We need to find the mass of the substance. We know that the density of an object is equal to the mass per unit volume. So,
d = m/V

How many atoms are in 123 g of calcium
Answer:
Molar mass of Ca = 40 g / mol , given 123 g Ca is 123/40= 3.075 moles,
1 mole = 6.022 * 10^23 atoms, so 3.075 moles Ca= 18.51*10^23 atoms
Explanation:
The number of atoms present in 123 g of calcium is 18.51 x 10²³ atoms.
What is calcium?Calcium is an element present in the periodic table. It is very much needed for the strength of the bones and teeth.
"Molar mass of many compounds can be calculated by dividing the mass of the compound by the number of moles of the compound."
"The mole is a SI unit of measurement that is used to calculate the quantity of any substance".
First, calculate the moles
Moles = mass / molar mass
Molar mass of Ca = 40 g / mol
Given 123 g Ca is mass
123 / 40 = 3.075 moles,
1 mole = 6.022 x 10²³ atoms,
6.022 x 10²³ is the Avogadro number. It equals to one mole.
So 3.075 moles Ca= 18.51 x 10²³ atoms.
Thus, the number of atoms present in 123 g of calcium is 18.51 x 10²³ atoms.
