Question

An experiment shows that a 116 −mL gas sample has a mass of 0.169 g at a pressure of 699 mmHg and a temperature of 34 ∘C. What is the molar mass of the gas?

Answer 1

We use the ideal gas law to calculate the Molar mass of the gas-

$PV=nRT$

$PV=(m/M)RT$

where 'm' is the mass taken in the due process and 'M' is the Molar mass of the gas-

Hence Molar mass of the gas is - 146.17 g.mol-1.
