Calculate the mass percent composition of carbon in each compound.
Step 1 of 3
Molecular mass of C2H2 = 26.0 g C2H2. 2 C = 12.0 g x 2 = 24.0 g C
% C = [(24.0 g C) / (26.0 g C2H2)] x 100 = 92.3 % C
Molecular mass of C3H6 = 42.1 g C3H6. 3 C = 12.0 g x 3 = 36.0 g C
% C = [(36.0 g C) / (42.1 g C3H6)] x 100 = 85.5 % C
Molecular mass of C2H6 = 30.1 g C2H6. 2 C = 12.0 g x 2 = 24.0 g C
% C = [(24.0 g C) / (30.1 g C)] x 100 = 79.7 % C
C2H6O: Mass % C = 24.022 x 100 / 46.0687 = 52.14 (Dimethyl Ether)
