Chapter 11, Problem 11.95AQAP

Interpretation Introduction

Interpretation:

We need to calculate the molar mass of the sample gas under given conditions.

Concept Introduction:

The ideal gas law provide the relation between pressure, temperature, volume and number of moles. The ideal gas equation can be written as;

PV = nRT

Here:

P = Pressure (atm)

V = volume (L)

n = moles of gas

R = gas constant = 0.0821 L.atm/ K.mol

T = Temperature (K)

  $\text{Number of moles (n) = }\frac{\text{Mass }\left(\text{g}\right)}{\text{Molar mass of gas }\left(\text{g/mol}\right)}$
