Contribution of each element
Element	Atoms, n	Atomic weight, A	n × A, g/mol Mass fraction, w	Mass fraction, w
Ccarbon	4	12.011	48.044 w ≈ 41.39%	≈ 41.39%
Hhydrogen	4	1.0080	4.0320 w ≈ 3.47%	≈ 3.47%
Ooxygen	4	15.999	63.996 w ≈ 55.13%	≈ 55.13%
Σ = 116.072 g/mol w = 100%				100%

Each fraction is rounded on its own, so the printed ones add up to 99.99%; unrounded, they make exactly 100%.
