Hi there,

☆ find the no of moles for each element in the compound

n (C) = 65.5 ÷ 12 = 5.46

n (H) = 5.5 ÷ 1 = 5.5

n (O) = 29.0 ÷ 16 = 1.8

☆ find the mole ratio by dividing over the lowest mole value which is 1.8

● C = 5.45 ÷ 1.8 = 3

● H = 5.5 ÷ 1.8 = 3

● O = 1.8 ÷ 1.8 = 1

☆ The empirical formula is C3H3O

♡ Hope the answer helps

Answer: C3H3O

Explanation:

Carbon                                                hydrogen                 Oxygen    

mass                           65.5                     5.5                         29.0              

Ar                                 12                       1                                  16

no of moles        5.458333333            5.5                             1.8125

                          1.8125                        i.8125                           1.8125
