Chapter 8, Problem 8.75QP

(a)

Interpretation Introduction

Interpretation: for the given reaction, the balanced equation, the percent purity of sample and the assumption are needed to be determined.

Concept introduction:

• Balanced chemical equation of a reaction is written according to law of conservation of mass.
• Equation for Number of moles of a substance, from its given mass is,

$\text{Number of moles}\text{=}\frac{\text{Given}\text{mass}}{\text{Molecular}\text{mass}}$

• Percent yield of reaction is the ratio of mass of actual yield to the mass of theoretical yield and multiplied with hundred.
