What is the molarity of a solution that contains 2.38 g of h2c2o4 * 2h2o in exactly 300 ml of solution?

Data Given:

Mass of H₂C₂O₂.2H₂ O = 2.38 g

M. mass of H₂C₂O₂.2H₂O = 126 g/mol

Volume = 300 ml = 0.3 dm³

Solution:

Molarity is given as,

Molarity = Moles / Vol. of Sol.

Or,

Molarity = (Mass / M. mass) * (1 / Vol)

Putting Values,

Molarity = (2.38 g : 126 g/mol) * (1 : 0.3 dm³)

Molarity = 0.063 mol/dm³
