The molecular mass of a 2.66g sample of gas at a temperature of pressure of 845torr and occupying a volume of 0.70L is 84.16g/mol.

How to calculate molecular mass?

The molecular mass can be calculated by first calculating the number of moles using the following formula:

PV = nRT

Where;

  • P = pressure
  • V = volume
  • n = no of moles
  • R = gas law constant
  • T = temperature

1.112 × 0.7 = n × 0.0821 × 300

0.7784 = 24.63n

n = 0.032mol

molecular mass = 2.66g ÷ 0.032mol

molecular mass = 84.16g/mol

Therefore, the molecular mass of a 2.66g sample of gas at a temperature of pressure of 845torr and occupying a volume of 0.70L is 84.16g/mol.
