A 0.879 g sample of a CaCl22H2O/K2C2O4·H2O solid salt mixture is dissolved in ~100 mL of deionized water. The precipitate, after having been filtered and air-dried, has a mass of 0.284 g.  The limiting reactant in the salt mixture was later determined to be CaCl2·2H2O.   How many moles and grams of the excess reactant, K2C2O4H2O, reacted in the mixture?             How many grams of the K2C2O4H2O in the salt mixture remain unreacted (in excess)?         What is the percent by mass of each salt in the mixture
