Chapter 4, Problem 152SAE

Interpretation Introduction

Interpretation:

Correct option needs to be determined for the mole of nitric acid that can be obtained from 4 moles of ammonia.

Concept introduction:

In Ostwald process nitric acid synthesis, the first step is catalytic oxidation of ammonia which is converted to nitric acid in later steps.

The number of moles can be calculated from mass and molar mass of the species as follows:

$n=\frac{m}{M}$

Here, m is mass and M is molar mass.
