Contribution of each element
Element	Atoms, n	Atomic weight, A	n × A, g/mol Mass fraction, w	Mass fraction, w
Ninickel	1	58.693	58.693 w ≈ 49.45%	≈ 49.45%
Ccarbon	1	12.011	12.011 w ≈ 10.12%	≈ 10.12%
Ooxygen	3	15.999	47.997 w ≈ 40.44%	≈ 40.44%
Σ = 118.701 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%.
