Given the following equation: NH3 +O2 �¨ NO + H2O

Calculate the number of grams of ammonia needed to form 40.12 moles of nitrogen monoxide.

ok so is this how its to look

4(NH3) + 5(O2) --> 4NO + 6(H20)

ok, you want 40moles of NO, so the ratio of ammonia to NO is 4:4, so you need 40 moles NH3. Convert that to grams.

Yes, you need to do it more accurately.
so then would it look like N= 14.01 and h= 1.008 add them and times by 40?
