How can I find the percent compositions of N2S2?
To find the percent composition of N₂S₂, you divide the total mass of each atom by the molecular mass and multiply by 100 %.
% by mass =
Mass of 2 N atoms = 2 N atoms ×
Mass of 2 S atoms = 2 S atoms ×
Mass of 1 N₂S₂ molecule = (28.02 + 64.12) u = 92.14 u
% of N =
% of S =
