The reaction of flourine with ammonia produces dinitrogen tetrafluoride and hydrogen fluoride.

5F2(g) + 2NH3(g) ==> N2F4(g) + 6HF(g)

a)If you have 66.6 g NH3, how many grams of F2 are required for complete reaction?
b)How many grams of NH3 are required to produce 4.65g HF?
c)How many grams of N2F4 can be produced from 225g F2?
