$M_{r} ({CH}_{3} {CO}_{2} H) = 60$ $"M"_r("CH"_3"CO"_2"H") = 60$

$M ({CH}_{3} {CO}_{2} H) = 60 g/mol$ $M("CH"_3"CO"_2"H") = 60"g/mol"$ OR $60 g \cdot {mol}^{- 1}$ $60"g"*"mol"^(-1)$

Explanation:

Given that:

$Relative Atomic Mass (A_{r}) (H) = 1$ $"Relative Atomic Mass"("A"_r)("H")=1$
$A_{r} (C) = 12$ $"A"_r("C") = 12$
$A_{r} (O) = 16$ $"A"_r("O") = 16$

$Relative Molecular Mass (M_{r}) ({CH}_{3} {CO}_{2} H) = 4 \times A_{r} (H) + 2 \times A_{r} (C) + 2 \times A_{r} (O)$ $"Relative Molecular Mass"("M"_r)("CH"_3"CO"_2"H") = 4xx"A"_r("H") + 2xx"A"_r("C") + 2xx"A"_r("O")$
$M_{r} ({CH}_{3} {CO}_{2} H) = (4 \times 1) + (2 \times 12) + (2 \times 16)$ $"M"_r("CH"_3"CO"_2"H") = (4xx1) + (2xx12) + (2xx16)$
$M_{r} ({CH}_{3} {CO}_{2} H) = 4 + 24 + 32$ $"M"_r("CH"_3"CO"_2"H") = 4 + 24 + 32$
$M_{r} ({CH}_{3} {CO}_{2} H) = 60$ $"M"_r("CH"_3"CO"_2"H") = 60$

Finally, acetic acid's relative molecular mass expressed as a molar mass:

$M ({CH}_{3} {CO}_{2} H) = 60 g/mol$ $M("CH"_3"CO"_2"H") = 60"g/mol"$ OR $60 g \cdot {mol}^{- 1}$ $60"g"*"mol"^(-1)$
