Chapter 7, Problem 7.73P

Interpretation Introduction

Interpretation:

The sample with more mass needs to be determined.

Sample of 2.0 L of O₂ at 273K and 500mmHg or sample of 1.5 L of N₂ at 298K and 650mmHg.

Concept Introduction:

The concept of ideal gas will be used. The ideal gas equation is represented as follows:

  $P=\frac{nRT}{V}$

Here,

n = number of moles

P = pressure

V = volume

R = gas constant

T = temperature

Also,

  $m=n\times M$

Here, m is mass, n is the number of moles and M is molar mass.
