5 The non ideal molar volume of gaseeris He is approximately 204/mol, What is the density of the gas 20l/mol / Imole 4g He =

Answer 1

Answer #1

Molar volume of gaseous He = 20 L/mol

Hence, 1 mole of He gas has volume = 20L

Also, molar mass of He gas = 4 g ( approx)

Therefore, 1 mole of He gas has mass = 4 g

Now, density = mass / volume = 4 g / 20 L = 0.2 g/L ( answer )
