In NH3, N = 14/17*100 = 82.4%

In NH4Cl, N = 14/53.5*100 = 26.2%

In NH4NO3, N = 28/80*100 = 35%

In (NH3)2SO4, N = 28/132*100 = 21.21%

So NH3 contain the highest number of Nitrogen.

you are the one that is wrong percentage deal with 100 so is correct the way he solve it and if you are ask to solve for percentage in something meaning the toatl mass over the mass of what you are ask to solve multiply by 100 which shows that nitrogen is heighest in A
