Hi so i am currently studying yr12 chem and am revising for my mocks. Im going over reacting mass calculations and im so lost. Please can someone help. The question is:
In the manufacture of ammonia, what mass of ammonia can theoretically be formed when 1kg if nitrogen reacts with 0.5kg of hydrogen. N2 + 3H2 > 2NH3
I did 1/28 = N2 moles = 0.0357
Then 0.5/2 = 0.25 0.25/3=0.083 = H2 moles
So N2 is limiting so you do 0.0357x17= 0.607kg of 2NH3 ??
But i cant see where Im going wrong but my paper is saying the answer is 1210g ??
Please can someone explain, thanks
