A 0.972g sample of CaCl2.2H2O/K2C2O4.H2O 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 0.375g the limiting reactant in the salt mixture was later determined to be CaCl2.2H2O
A. What is the % by mass of CaCl2.2H2O in the salt mixture
B. how many grams of the excess reactant K2C2O4.H2O reacted in the mixture
C. How many grams of the K2C2O4. H2O in the salt mixture remain unreacted
