Question

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 0.253 g.
The limiting reactant in the salt mixture is K2C2O4⋅H2O. Determine Mass of K2C2O4⋅H2O(aq) in Salt Mixture in grams.

Answer 1

CaC2O4 = 0.253 g
0.253 x (molar mass K2C2O4.H2O/molar mass CaC2O4) = ? g K2C2O4.H2O

Answer 2

.362425

Answer 3
