What is the percent composition for all the elements in ammonium sulfite? 4). % N ______ 5). % H ______ 6). % S ______ 7). % O ______

Answer 1

ammonium sulfite is (NH₄)₂SO₃ with a molar mass of 116 g/mole

Taking a look at the composition of this compound, we see the following:

2 N x 14 = 28 g N

8 H x 1 = 8 g H

1 S x 32 = 32 g S

3 O x 16 = 48 g O

Totaling 116 g/mole

PERCENT COMPOSITION:

%N = 28 g/116 g (x100%) = 24.1% N

%H = 8 g/116 g (x100%) = 6.9% H

%S = 32 g/116 (x100%) = 27.6% S

%O = 48 g/116 g (x100%) = 41.4% O

Total = 100%
