N2(g) + 3H2(g) -> 2NH3(g)

How many grams of ammonia are formed from 14.0 grams of nitrogen?

14/2 = 7 grams of ammonia

1 answer

The equation is balanced, For each mole of N2 (nitrogen), twice that number of moles of ammonia is formed.

moles nitrogen= 14/28=.5 moles
moles ammonia= 2*.5=1
grams ammonia= (14+3)*1 = 17 grams.
