What is the molar mass of KSCN?

Answer

M(KSCN) ≈

97.18 g/mol

Atomic weights: IUPAC standard values (CIAAW, 2024); the sum is rounded to the decimal places of the least precise one — S: 32.06.

Contribution of each element
Element	Atoms, n	Atomic weight, A	n × A, g/mol Mass fraction, w	Mass fraction, w
Kpotassium	1	39.098	39.098 w ≈ 40.23%	≈ 40.23%
Ssulfur	1	32.06	32.06 w ≈ 32.99%	≈ 32.99%
Ccarbon	1	12.011	12.011 w ≈ 12.36%	≈ 12.36%
Nnitrogen	1	14.007	14.007 w ≈ 14.41%	≈ 14.41%
Σ = 97.176 ≈ 97.18 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%.
