For this problem, we are being asked to determine the empirical formula with the given mass % of H and C.
moles C = 6.66 mol
moles H = 19.80 mol
We need to divide the number of moles of each by the smallest value, 6.66 mol, to get the smallest ratio of C and H.
Based on the mole ratio you determined in Part C, what is the empirical formula of this compound?
Information for Parts B, C, and D
A compound is 80.0% carbon and 20.0% hydrogen by mass. Assume a 100.-g sample of this compound.
