Contribution of each element
Element	Atoms, n	Atomic weight, A	n × A, g/mol Mass fraction, w	Mass fraction, w
Ccarbon	7	12.011	84.077 w ≈ 79.23%	≈ 79.23%
Hhydrogen	6	1.0080	6.0480 w ≈ 5.70%	≈ 5.70%
Ooxygen	1	15.999	15.999 w ≈ 15.08%	≈ 15.08%
Σ = 106.124 g/mol w = 100%				100%

Each fraction is rounded on its own, so the printed ones add up to 100.01%; unrounded, they make exactly 100%.
