Question

Determine the mass percentage of carbon, C, hydrogen, H, and oxygen, O, in C₈H₁₆O₂.

Answer 1

C = 67%

O = 22%

H = 11%

Step-by-step explanation:

Given C = 12, O = 16, H = 1

C8 = 8(12) = 96

O2 = 2(16) = 32

H16 = 16(1) = 16

Total molar mass = 96 + 32 + 16 = 144

% of C = 96/144 = 0.67 = 67%

% of O = 32/144 = 0.22 = 22%

% of H = 16/144 = 0.11 = 11%
