A 0.879-g sample of a CaCl2x2H2O/K2C2O4xH2O solid salt mixture is dissolved in 150 mL of deionized water, previously adjusted to a pH that is basic. The precipitate, after having been filtered and air-dried, has a mass of .284 g. The limiting reactant in the salt mixture was later determined to be CaCl2x2H2O.

a. How many moles and grams of CaCl2*2H2O reacted in the reaction mixture?
b. How many moles and grams of the excess reactant, K2C2O4*H2O, reacted in the mixture?
c. How many grams of the K2CaO4*H2O in the salt mixture remain unreacted?
d. What is the percent by mass of each salt in the mixture?
