Chapter 8, Problem 8.95QP

Interpretation Introduction

Interpretation: for the given sequence of reaction, the number of moles of product ${\text{NH}}_{\text{4}}{\text{V}}_{\text{3}}{\text{O}}_{\text{8}}$ formed from 2 moles of ${\text{N}}_{\text{2}}\text{and}{\text{H}}_{\text{2}}$ to be determined.

Concept introduction:

• Balanced chemical equation of a reaction is written according to law of conservation of mass.
• Mole ratio between the reactant and a product of a reaction are depends upon the coefficients of reactant and product in a balanced chemical equation.
• Number of moles of a substance,

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

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

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