Answer : The volume of helium gas is, 244.72 liters
Explanation : Given,
Mass of helium gas = 43.7 g
Molar mass of helium gas = 4 g/mole
As we know that at STP, 1 mole of gas contains 22.4 liter volume of gas.
First we have to calculate the moles of helium gas.
Now we have to calculate the volume of helium gas.
As, 1 mole of helium gas contains 22.4 liter volume of gas
So, 10.925 mole of helium gas contains liter volume of gas
Therefore, the volume of helium gas is, 244.72 liters
