Question

calculate the molar mass of oxalic acid. (H=1, C=12,O=16)​

Answer 1

Answer:

90

Explanation:

(COOH) 2

2*12+4*16+2*1

24+64+2

90

Answer 2

The molar mass of oxalic acid is 90.

Given: Oxalic acid.

To find The molar mass of oxalic acid.

Solution:

The chemical formula of oxalic acid is (COOH)2.

or $C_2H_2O_4$.

The atomic mass of a carbon atom is 12.

The atomic mass of hydrogen is 1.

The atomic mass of oxygen is 16.

Thus the molar mass of oxalic acid will be-

$2 \times 12 + 2 \times 1 + 4 \times 16 \\ 24 + 2 + 64 \\ = 90$

Thus the molar mass of oxalic acid is 90.
