Chapter 5, Problem 5.34P

Interpretation Introduction

Interpretation: The molar mass of the gas needs to be calculated if the mass of the gas is 206 ng and volume is $0.206\mu \text{L}$ at given temperature and pressure values.

Concept Introduction: An ideal gas equation is represented as follows:

  $PV=nRT$

Here, P is pressure, V is volume, n is number of moles, R is Universal gas constant and T is temperature of the gas.

Number of moles can be calculated from mass and molar mass as follows:

  $n=\frac{m}{M}$

Here, m is mass and M is molar mass.
