Chapter 13.10, Problem 13.12SC

Interpretation Introduction

Interpretation:

The volume of sample of ammonia gas at STP should be determined.

Concept Introduction:

The volume of ammonia gas at STP can be determined using ideal gas law. Ideal gas law isa hypothetical law and is mathematically expressed as:

PV = nRT

Where,

P is the pressure of gas

V is the volume of the gas

T is the absolute temperature of the gas

R is the gas constant and

n is the number of moles of the gas molecules

The ideal gas law can also be represented as:

$\frac{{\text{P}}_1{\text{V}}_1}{{\text{T}}_1}=\frac{{\text{P}}_2{\text{V}}_2}{{\text{T}}_2}$

The ratio $\left(\frac{\text{P}\text{V}}{\text{T}}\right)$ of a gas is always constant.
