This is another question on my chemistry worksheet.

I guess they want the definition because there are no numbers involved.

What gas? what temperature? what pressure?
it doesn't give any of those. it is a short answer question and the only thing it says is what is a gas's molecular mass?
The molar mass of a gas is the mass of 22.4 liters of the gas at STP.
