Nitrogen gas reacts with hydrogen gas to produce ammonia by the following equation.
N2(g) + 3H2(g) ---> 2NH3(g)
A: If you have 3.98g of H2, how many grams of NH3 can be produced?
B: How many grams of H2 are needed to react with 3.00g of N2?
C: How many grams of NH3 can be produced from 19.0g of H2?
