Chapter 11.8, Problem 11.70QAP

Interpretation Introduction

Interpretation:

The mass of ammonia in grams should be determined which is produced when 4.00 L of nitrogen dioxide reacts at 415°C and 725 mmHg.

Concept Introduction:

Ideal gas law gives the relationship between pressure (P), volume (V), temperature (T) and amount of gas or number of moles (n).

The equation for Ideal gas law is:

PV = nRT

Where, P = pressure of a gas

V = volume of a gas

n = number of moles of a gas

T = temperature of a gas

R = Ideal gas constant ( $\text{62}\text{.4 }\frac{\text{L}\text{.mmHg}}{\text{mol}\text{.K}}$ )

Number of moles is defined as the ratio of given mass to the molar mass.

The mathematical expression is given by:

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