Question

1) Calculate the empirical formula of a compound with 36g of carbon and 96g of oxygen.

Answer 1

C4H6

Step-by-step explanation:

See attached table

Convert each of the masses into moles by dividing the mass by the molar mass of that element. That yields 3.83 moles of C and 6 moles of O. I rounded up the C to 4 moles to result in an empirical formula of C4H6
