Answer: CH
Explanation: To calculate the empirical formula of the compound we must first find the number of moles by using the mass of each element.
C= 92.31 g x 1mole C / 12 g C
= 7. 69 moles C
H = 7.69 g H x 1 mole H/ 1 g H
= 7.69 moles H
Next is divide each answer on the lowest number of moles
C = 7.69 / 7.69 = 1
H = 7.69 / 7.69 = 1
So the ratio is 1:1 or CH
