I need help setting up these problems
1. a container with a volume of 893 L contains how many moles of air at STP?
2. A chemical reaction produces 0.37 mol of N2 gas. What volume will that gas occupy at STP?
Thanks for the help!!!

1. 893 L*1 mol/22.4 L=39.9 mol
2. .37 mol*22.4 L/1 mol=82.9 L

Question 1. Go back to PV=nRT. You have V, T, and P. R is a constant. Your teacher should have told you what STP (a.k.a. standard conditions) are. I would give you the answer outright but it's so much fun and satisfying to do it yourself.
Question 2. Again go back to PV=nRT. If you answer question 1, you can easily answer question 2.

ahhh I took chem last year lets see....
set it up using the factor label method, and use the factor that 22.9 L of gas is one mole. I think. Might want to double check that number though it's off the top of my head.
