This is due in on Monday and I honestly have no clue where to start:
Ammonia is made by reaction of nitrogen with Hydrogen
N2+3H2=2NH3
calculate the maximum mass of ammonia that could be formed from reaction of 12g of Hydrogen reacting with nitrogen

b)In this reaction only 15g of ammonia was formed calculate the percentage yield

1. Find number of moles of hydrogen molecules, use mol ratio to obtain the number of moles for ammonia, then multiply by relative molecular mass of ammonia

2.calc the number of moles of ammonia (x)
number of moles of h2 (y)

x and y are already the numbers obtained using the mol-ratio : (x/y) *100%

i hope this helped
