Contribution of each element
Element	Atoms, n	Atomic weight, A	n × A, g/mol Mass fraction, w	Mass fraction, w
Ccarbon	12	12.011	144.132 w ≈ 36.25%	≈ 36.25%
Hhydrogen	19	1.0080	19.1520 w ≈ 4.82%	≈ 4.82%
Clchlorine	3	35.45	106.35 w ≈ 26.75%	≈ 26.75%
Ooxygen	8	15.999	127.992 w ≈ 32.19%	≈ 32.19%
Σ = 397.626 ≈ 397.63 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%.
