A sample of CaCl2⋅2H2O/K2C2O4⋅H2O solid salt mixture is dissolved in ~150 mL

de-ionized H2O. The oven dried precipitate has a mass of 0.24 g.

The limiting reactant in the salt mixture is K2C2O4⋅H2O.

CaCl2⋅2H2O(aq) + K2C2O4⋅H2O(aq) à CaC2O4⋅H2O(s) + 2KCl(aq) + 2H2O(l)

Molar Mass (MM) g/mol:

CaCl2⋅2H2O = 147.02 K2C2O4⋅H2O = 184.24 CaC2O4 = 128.10

Determine Mass of K2C2O4⋅H2O(aq) in Salt Mixture in grams.
