Calculate the percentage, by mass, of carbon in cyclohexane. Give your answer to two significant figures.
formua of cyclohexane C6H12
molar ratio is 1:2 (divide 6 and 12 by 6 )
to get mass ratio multiply by molar mass (1 x 12 and 2x1)
12:2
convert to percentage (12/14 = 6/7 = 85.7% carbon by mass )
