Answer 1

Answer:

Explanation:

126.07 g/mol

Oxalic acid, H2C2O4*2H2O (molar mass = 126.07 g/mol) is oftenused as a primary standard for the standardization of a NaOHsolution.

Answer 2

Answer:

The molecular weight of H2C2O4•2H2O is 126 g/mole .

Explanation:

The molecular weight means the molecular mass of the molecule.

Molecular mass can be calculated by adding the atomic masses of the atoms present in the molecule.

in the molecule H2C2O4•2H2O, the atoms which present in the molecule are Hydrogen , Carbon, and Oxygen.

There are 6 number of Hydrogen atom, 2 number of Carbon atom and 6 number of Oxygen atoms.

So the molecular mass of H2C2O4•2H2O = 6× atomic mass of Hydrogen + 2× Atomic mass of Carbon + 6× atomic mass of Oxygen.

= 6×1 + 2×12 + 6×16

= 6 + 24 + 96

= 126 g/mole

Conclusion:.

The molecular weight of H2C2O4•2H2O is 126 g/mole .
