Well let's see:

H = 1g

O = 16g

N = 14g

H2O = 18g per mole (1 + 1 + 16)

NH3 = 17g per mole (14 + 1 + 1)

18 x 5 = 90

17 x 3.5 = 59.5

90>59.5

.: 5.0 mol H2O has a greater mass than 3.5 mol of NH3

What is the mass percentage of N in NH3?

Nitrogen has an average atomic mass of about 14 while hydrogen has an average atomic mass of about 1, so the total molecular mass of NH3 is about 17. From this we find that the mass percentage of N in NH3 is about 14/17 = 82%. To get more precise numbers, look up the exact atomic masses from a periodic table.
