Chapter 8, Problem 8.78QP

Interpretation Introduction

Interpretation: the mass of $\text{CaO}$ required treat with sulfur dioxide in the given reaction to be determined when $\text{6}\text{.6}\text{×}{\text{10}}^{\text{6}}\text{kg}$ of coal is used.

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.
