Calculate the molar mass of Acetic acid, ${\mathrm{CH}}_3\mathrm{COOH}$

Given the atomic masses of C = 12u, H = 1u, O = 16u

Step 1: Calculating the molar mass

Molar mass is equal to the sum of atomic masses of the individual atoms present in one molecule of a substance.

Step 2: Given data

Atomic masses: C = 12u, H = 1u, O = 16u

Step 3: Finding the molar mass for the given data

The molar mass of ${\mathrm{CH}}_3\mathrm{COOH}$ = (Number of carbon atoms x atomic mass of carbon) + (Number of hydrogen atoms x atomic mass of hydrogen) + (Number of oxygen atoms x atomic mass of oxygen)

The molar mass of ${\mathrm{CH}}_3\mathrm{COOH}$ = $\left(1\times 12\right)+\left(3\times 1\right)+\left(1\times 12\right)+\left(2\times 16\right)+\left(1\times 1\right)$

The molar mass of ${\mathrm{CH}}_3\mathrm{COOH}$ = $12+3+12+32+1=60$g/mol

Hence, the molar mass of Acetic acid ${\mathrm{CH}}_3\mathrm{COOH}$ is $60$g/mol
