Chapter 9, Problem 14ALQ

Interpretation Introduction

Interpretation:

In a chemical reaction, other than the mass of each reactant, the criteria required to determine the mass of product is to be stated. The validation of the fact that the mass of product is not necessarily the sum of mass of reactants is to be stated with the help of an example.

Concept Introduction:

The number of moles is calculated by the formula,

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

Where, molar mass is the mass of one mole of a substance. One mole contains $6.022\times {10}^{23}$ atoms.
