Homework Statement
What is the percentage of carbon in dimethylsulfoxide, C2 H6 SO4?
Homework Equations
mass of C / total mass x 100 = percentage of carbon
The Attempt at a Solution
The total mass = 126
total mass of C = 24
Wouldn't it be 24 / 126 x 100 = 19 %
But somehow I got this wrong, it's 30.7 %
Any help will be appreciated, thanks a lot
