Quinine in a 1.664-g antimalarial tablet was dissolved in sufficient 0.10 M to give 500 mL of solution. A 15.00-mL aliquot was then diluted to 100.0 mL with the acid. The fluorescence intensity for the diluted sample at 347.5 nm provided a reading of 327 on an arbitrary scale. A standard 100 ppm quinine solution registered 180 when measured under conditions identical to those for the diluted sample. Calculate the mass of quinine in milligrams in the tablet.

Answers

Answer:

605.6mg of quinine

Explanation:

Based on Lambert-Beer's law, the intensity of an optical measurement is directely proportional to its concentration.

Unknown concentration gives a reading of 327

100 ppm gives 180 of intensity

The concentration of the diluted quinine tablet is:

327 * (100ppm / 180) = 181.67 ppm. The final dilution

The concentration of the first diluted solution is:

181.67 ppm * (100.0mL / 15mL) = 1211ppm

ppm could be defined as mass of solute (In this case of quinine) in mg per liter of solution. That is:

1211mg / L

As the tablet was diluted to 500mL = 0.5L, the mass of the quinine is:

0.5L * (1211mg / L) =

605.6mg of quinine

Which type of formula shows an element symbol for each atom and a line for each bond between atoms?

structural
molecular
empirical
ionic

Answers

Answer: structural

Explanation:

When metals and non metals combine in fixed proportion then a chemical compound is formed. Structural formula shows an element symbol for each atom and a line for each bond between atoms. The correct option is option A.

What is chemical formula?

Chemical formula is a formula where cation and anion combine to form a molecule in fixed proportion. Metals combine in form of cation and non metals combine in form of anion.

Cation is the species that give electron and attain positive charge while anion is a species which gain electron and attains negative charge so when anion and cation combine in fixed ration the the overall charge of the molecule is zero that is molecule is neutral.

Out of given structural is a 3D representation of any chemical formula, in which symbol of each element is shown .Along with symbol line for each bond between atoms is also shown.

Therefore, the correct option is option A.

A 0.530 M Ca(OH)2 solution was prepared by dissolving 36.0 grams of Ca(OH)2 in enough water. What is the total volume of the solution thus formed? (4 points)

Answers

Answer:

0.917 L

Explanation:

Step 1: Given data

Molar concentration of the solution (M): 0.530 M (0.530 mol/L)Mass of Ca(OH)₂ (solute): 36.0 g

Step 2: Calculate the moles corresponding to 36.0 g of Ca(OH)₂

The molar mass of Ca(OH)₂ is 74.09 g/mol.

36.0 g × 1 mol/74.09 g = 0.486 mol

Step 3: Calculate the volume of the solution

Molarity is equal to the moles of solute divided by the liters of solution.

M = moles of solute / liters of solution

liters of solution = moles of solute / M

liters of solution = 0.486 mol / (0.530 mol/L) = 0.917 L

Answer:

0.917 liters
