The Haber process is used to synthesize ammonia from hydrogen and nitrogen. How much hydrogen is required to produce 42.8 kg of ammonia?

Answer 1

N2 + 3H2 ==> 2NH3

mols NH3 = grams/molar mass = 42800/17 = ?

Using the coefficients in the balanced equation, convert mols NH3 to mols H2.
Now convert mols H2 to grams. g = molx x molar mass.
