For the percent by mass C, we’re going to rewrite the equation as:
Mass of C:
2 x 12.01 g/mol = 24.02 g/mol
Molar mass of C2H6SO:
C: 2 x 12.01 g/mol = 24.02 g/mol
H: 6 x 1 .01 g/mol = 6.06 g/mol
S: 1 x 32.07 g/mol = 32.06 g/mol
O: 1 x 16.00 g/mol = 16.00 g/mol
What is the mass % of carbon in dimethylsulfoxide, C2H6SO?
