Chapter 21, Problem 21.132MP

Interpretation Introduction

Interpretation:

From the given data, the mass percent of iron in steel 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 liters). The molarity of a solution can be given by the formula,

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