Question

How to calculate molecular weight of oxalic acid?

Answer 1

Answer:

90 amu

Explanation:

Molecular formula of Oxalic Acid = C2H2O4

Atomic mass of -

C = 12 amu

H = 1 amu

O = 16 amu

12*2 + 1*2 + 16*4

24 + 2 + 64

90 amu

Answer 2

$\huge\sf\underline\pink {\underline{"AnSwEr:"}}$

$\small\sf\purple{90.03 g/mol}$

$\small\sf\red{Formula: C2H2O4}$

$\small\sf\green{Density: 1.9 g/cm³}$

• Thus, the equivalent weight of oxalic acid can be calculated as follows: Equivalent mass of oxalic acid = molecular mass of oxalic acid/2 = 126g/2 = 63 grams. Therefore, the equivalent weight of oxalic acid is 63 grams.
