Chemistry Problem..

Well seeing how you didn't acknowledge my last answer I'll be on my way.

(slams hat on head and storms out, slamming door behind)

I guess I'd rather be ignored than insulted, so I'll pitch hit for brother Hingehead, and offer a nudge in the right direction.

Step One. Use the Ideal Gas Law three times, once for each of the three reactants. Determine how many gram moles are present for each of the three reactants.

Step Two. From the reaction stoichiometry ( 2:2:3 ), determine which of the three reactants is the limiting reactant. This controls how much (in gram moles) of reaction will occur.

One general hint - you frequently know how to proceed in working a school chemistry problem by the information provided. You will use all the information given, and no information is needed except for what is given (except for general information, such as molecular weights). You don't have this advantage when you go to work. No one gives you all the information you need.
