My teacher is going to list the molar masses of five gases and ask us which has the largest molar volume at STP. How would I go about solving this?

Would the smallest number have the largest volume?

I'm a little confused. The molar volume of an ideal gas at STP is 22.414L. Therefore, for an ideal gas, it wouldn't make any difference which gases were chosen, the answer would be 22.414 L. Perhaps the teacher is giving a real gas and you are to use the van der Waals equation.
Maybe, so in that case I would just have to plug everything into the van der waals equation to find the answer?
yes or look at the values for a and b and see how that affects the final answer.
Ok thank you!!
