What is the molar mass of SrSO₄?

Answer

M(SrSO₄) ≈

183.68 g/mol

Atomic weights: IUPAC standard values (CIAAW, 2024); the sum is rounded to the decimal places of the least precise one — Sr: 87.62, S: 32.06.

Contribution of each element
Element	Atoms, n	Atomic weight, A	n × A, g/mol Mass fraction, w	Mass fraction, w
Srstrontium	1	87.62	87.62 w ≈ 47.70%	≈ 47.70%
Ssulfur	1	32.06	32.06 w ≈ 17.45%	≈ 17.45%
Ooxygen	4	15.999	63.996 w ≈ 34.84%	≈ 34.84%
Σ = 183.676 ≈ 183.68 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%.
