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
