Chapter 27.4, Problem 6TY

Interpretation Introduction

Interpretation:

The weight percentage of carbon and hydrogen in given sample has to be calculated.

Concept introduction:

The mass percentage of compound can be calculated by dividing the calculated mass of the substance to the total mass of the sample whole multiplied by 100.

The mass percent can be calculated with formula,

$\text{Mass}\text{percent(in}\text{percentage)=}\frac{\text{Calculated}\text{mass(in}\text{grams)}}{\text{total}\text{mass(in}\text{grams)}}\text{×100}$

Molarity can be defined as the moles of solute to the volume of the solution (in litres). The molarity of a solution can be given by the formula,

$\text{Molarity(M)=}\frac{\text{Moles}\text{of}\text{solute(in}\text{mol)}}{\text{Volume}\text{of}\text{solution(in}\text{L)}}$
