Calculate the volume of 42 kg of helium gas.

Question

Answer is 235,200L.

 

ps. How do I get to the answer by using mole highway? Thx!

Answer 1

They are assuming STP conditions, where 1 mole of any gas occupies 22.4 L

42 kg He x 1000 g/kg x 1 mole He/4 g = 10,500 moles of He

10,500 moles He x 22.4 L/mole = 235,200 Liters

 

Answer 2

 

Hi Nic

The given information is not sufficient to get the answer. How closely packed it is ? Temp? Pressure ?
