(Popcorn Stand) A salt shaker has 2.91 moles of NaCl, how many grams of NaCl are in the salt shaker?
Answer:
170 grams NaCl
Explanation:
Find the mass of NaCl by adding the two elements atomic mass
Na: 22.99
Cl: 35.45
22.99+35.45=58.44 g
Convert moles to grams.
2.91 mol NaCl * 58.44 g NaCl= 170.0604 g

moles
Answer:
Here pressure Volume and temperature are given, answer can be feched by applying the equation PV = nRT
The variables which are given in the problem are volume, pressure and temperature.
What are variables?Variables are defined as any characteristics, number or quantity which can be measured . It can also be called as a data item . It is called as variable because they can vary and can have variety of values.
There are three types of variables 1) manipulated variable where in a condition is specified, 2) responding variable which is dependent on manipulated variable 3)controlled variable which do not change.
Example of manipulated variables are number of hours spent by a student studying , that of responding variable is result of a student and temperature is an example of controlled variable.

What force is necessary to accelerate a 1,200 kg car at a rate of 35 m/s2?
How much acceleration would the car have if a 30,600 N force was applied to
the car?
Explanation:
Given that,
Mass of a car, m = 1200 kg
Acceleration of the car, a = 35 m/s²
The force acting on the car is given by :
F = ma
F = 1200 kg × 35 m/s²
= 42000 N
If the force is 30,600 N, then acecleration is given by :
[tex]a=\dfrac{F}{m}\\\\a=\dfrac{30600}{1200}\\\\a=25.5\ m/s^2[/tex]
Hence, this is the required solution.
the moon is 250,000 miles away. How many inches is it from earth?
Answer:
1.584e10 = 15,840,000,000,000
Explanation:
250,000 miles
