Chapter 3.12, Problem 1PPA

Interpretation Introduction

Interpretation:

Excess reactant is to be identified and the mass of ammonia and the amount of excess reactant left after the completion of reaction are to be calculated.

Concept introduction:

The balanced chemical reaction in the production of ammonia is represented below:

${\text{N}}_2\left(g\right)+{\text{3H}}_2\left(g\right)\to 2{\text{NH}}_3\left(g\right)$

The equation for calculating the number of moles(n) of a substance is shown below:

$$ $\text{No}\text{. of moles of the substance}\left(n\right)=\frac{\text{Mass of the substance}\left(\text{in g}\right)}{\text{Molar mass of the substance}\left(\text{in }\text{g}/\text{mol}\right)}$
