What is the molar mass of C₆H₅Cl?

Answer

M(C₆H₅Cl) ≈

112.56 g/mol

Atomic weights: IUPAC standard values (CIAAW, 2024); the sum is rounded to the decimal places of the least precise one — Cl: 35.45.

Contribution of each element
Element	Atoms, n	Atomic weight, A	n × A, g/mol Mass fraction, w	Mass fraction, w
Ccarbon	6	12.011	72.066 w ≈ 64.03%	≈ 64.03%
Hhydrogen	5	1.0080	5.0400 w ≈ 4.48%	≈ 4.48%
Clchlorine	1	35.45	35.45 w ≈ 31.50%	≈ 31.50%
Σ = 112.556 ≈ 112.56 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%.
