Answer» Answer: 0.63 g is the mass of OXALIC acid crystals required to prepare 50 ML of a 0.2 N solution. Explanation: - Oxalic acid EXISTS as the dihydrate C₂H₂O₄.2H₂O. Molecular weight of oxalic acid dihydrate = 126 g / mol. Gram equivalent weight = Molecular weight / basicity = = 63 g / mol 1 Normal solution of oxalic acid should have 63 g in 1 L. 0.2 Normal solution of oxalic acid should have = 12.6 g in 1 L. 0.2 Normal solution of oxalic acid should have in 50 mL. = 0.63 g in 50 mL.

Answer»

Answer:

0.63 g is the mass of OXALIC acid crystals required to prepare 50 ML of a 0.2 N solution.

Explanation: -

Oxalic acid EXISTS as the dihydrate C₂H₂O₄.2H₂O.

Molecular weight of oxalic acid dihydrate = 126 g / mol.

Gram equivalent weight = Molecular weight / basicity

= = 63 g / mol

1 Normal solution of oxalic acid should have 63 g in 1 L.

0.2 Normal solution of oxalic acid should have

= 12.6 g in 1 L.

0.2 Normal solution of oxalic acid should have in 50 mL.

= 0.63 g in 50 mL.
