Chapter 11.8, Problem 11.68QAP

Interpretation Introduction

Interpretation:

The volume of oxygen in litres should be determined.

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 ( $\text{62}\text{.4 }\frac{\text{L}\text{.mmHg}}{\text{mol}\text{.K}}$ ) or ( $\text{0}\text{.0821 }\frac{\text{L}\text{.atm}}{\text{mol}\text{.K}}$ )

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

The mathematical expression is given by:

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