Question

Calculate the molar mass of oxalic acid (C = 12u, O = 16u, H = 1u)

Answer 1

1. Molar mass is the sum of the masses of all the individual atoms present in a molecule or compound.
2. Oxalic acid is an organic acid that is present in leafy vegetables, fruits, and vegetables.
3. The chemical formula of oxalic acid is ${\left(\mathrm{COOH}\right)}_2$
4. The atomic mass of carbon C is 12u.
5. The atomic mass of hydrogen H is 1u.
6. The atomic mass of oxygen is 16u.
7. $\mathrm{Molar}\mathrm{mass}\mathrm{of}\mathrm{oxalic}\mathrm{acid}{\left(\mathrm{COOH}\right)}_2=(\mathrm{Atomic}\mathrm{mass}\mathrm{of}\mathrm{carbon})\mathrm{x}2+(\mathrm{Atomic}\mathrm{mass}\mathrm{of}\mathrm{Oxygen})\mathrm{x}4+(\mathrm{Atomic}\mathrm{mass}\mathrm{of}\mathrm{hydrogen})\mathrm{x}2$ $=(12\mathrm{x}2)+(16\mathrm{x}4)+(1\mathrm{x}2)$

$=24+64+2$

$=90\mathrm{g}$

The molar mass of oxalic acid ${\left(\mathrm{COOH}\right)}_2$ is 90g.
