Question

7. Find empirical formula of a compound that contains 85.6% carbon and 14.4% hydrogen.

Answer 1

So,

To find the empirical formula of this compound, what we're going to do is to follow up the steps:

Step 1: Pass all the percentages to grams: (Just change the unit)

Step 2: Divide each amount by the molecular weight. (Convert to moles):

Step 3: Divide each previous amount by the smaller value found:

Those values are the subscripts of the empirical formula. Therefore, the answer is that the empirical formula of the compound is CH2.
