Chapter 8.4, Problem 8.4.2SR

Interpretation Introduction

Interpretation:

The mass of ${\text{CaSO}}_{\text{4}}$ formed should be calculated by using the data’s given for the reaction.

Concept introduction:

• Mole ratios between the reactants and products of a reaction are depends upon the coefficients of respective reactant in a balanced chemical equation.
• Balanced chemical equation of a reaction is written according to law of conservation of mass.
• Number of moles of a substance, from its given mass is,

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

• Number of grams of a substance from its number of moles is,

  $\text{Number of moles}\text{×}\text{Molecular}\text{mass in grams}\text{=}\text{Number}\text{of}\text{grams}$
