Question

calculate the molar mass of oxalic acid (c=12,o=16,h=1)​

Answer 1

Thus, the molar mass of oxalic acid is 90 grams.

Given:

Oxalic acid.

To find:

Its molar mass.

Solution:

The given compound is oxalic acid.

The formula of oxalic acid is as follows-

$(COOH)_2$.

The atomic mass of C is 12 grams.

The atomic mass of oxygen is 16 and hydrogen is 1 gram.

This compound has four oxygen, two carbon and two hydrogen atoms.

Thus we can write-

$(12 + 16 \times 2 + 1) \times 2 \\ = (12 + 32 + 1) \times 2 \\ = 45 \times 2 \\ = 90$

Thus, the molar mass of oxalic acid is 90 grams.
