Calculate the mass percent of each of the elements in 3-phenylphenol, C12H10O

C = 84.71%

H = 5.88%

O =  9.41%

Given

3-phenylphenol, C12H10O

Required

The mass percent

Solution

Ar C = 12 g/mol

Ar H = 1 g/mol

Ar O = 16 g/mol

MW C12H10O = 170 g/mol

The mass percent :

C = (12x12/170) x 100%

C = 84.71%

H = (10x1)/170) x 100%

H = 5.88%

O = (1 x 16)/170 x 100%

O =  9.41%
