Can someone help me out with this one?

I have 105cm^3(2*100+10)/2)

So you know that equal volume of gases have equal volume at the same temperature and pressure.

It means 2V of X combines with 1 V of Y to give 2V of Z

One of the gases is the limiting reactant .Find out the limiting reactant and calculate volume of Z formed from limiting reactant and volume of gas left as excess reagent.

1V of Y combines with 2V of X

so.... 10mL of Y will combine with how much volume of X?

10mL of Y will give how much volume of Z?

How much volume of X left unreacted ?
