Expert Solution
Step 1

Given : The compound consist of only C, H and O.

Mass percent of C = 77.87 %

Mass percent of O = 10.37 %

Since the sum of mass percent of all the 3 elements should be 100 %

=> mass percent of H = 100 - Mass percent of C - Mass percent of O

=> mass percent of H = 100 - 77.87 - 10.37 = 11.76 % 

1) Assuming 100 g of the compound and the empirical formula of the compound as CaHbOc.
