The molar mass of the gas is 65.3 g/mol

How to determine the mole of the gas

  • Volume (V) = 0.854 L.
  • Temperature (T) = 302 K
  • Pressure (P) = 1.04 atm
  • Gas constant (R) = 0.0821 atm.L/Kmol
  • Number of mole (n) =?

The number of mole of the gas can be obtained by using the ideal gas equation as illustrated below:

PV = nRT

Divide both side by RT

n = PV / RT

n = (1.04 × 0.854) / (0.0821 × 302)

n = 0.0358 mole

How to determine the molar mass

  • Mass = 2.34 g
  • Number of mole = 0.0358 mole
  • Molar mass =?

Molar mass = mass / mole

Molar mass = 2.34 / 0.0358

Molar mass of gas = 65.3 g/mol
