Here is the question I have, I'm not sure if my answers are right. Please let me know.

1.) Consider the following reaction: 2N2 + 3O2 = 2N2O3

How many moles of dinitrogen trioxide will be formed if 15 moles of oxygen react? 
10 moles

How many liters?
224 liters

How many grams?
1,520 grams

How many grams of nitrogen will react with the 15 moles of oxygen?
560 grams

How many grams?
1,520 grams

How many grams of nitrogen will react with the 15 moles of oxygen?
560 grams

too high!

Molar weight of N2O3 = 76g/mol x 10moles = 760g

If 10 moles of N2 are required to form the 10 moles of N2O3, then we can multiply the 10 moles times the molar weight of N2, which is 28g/mol. That gives us 280g of N2 that would need to react.
