A 0879g sample of a cacl2x2h2ok2c2o4xh2o solid salt mixture, Ask an Expert

Academics

A 0.879g sample of a CaCl2x2H2O/K2C2O4xH2O solid salt mixture is dissolved in 150 mL of deionized water, previously adjusted to a pH hat is basic. The precipitate, after having been filtered and air-dried, has a mass of 0/284g. The limiting reactant in the salt mixture was later determined to be CaCl2x2H2O a) How many moles and grams of the excess reactant, K2C2O4xH2O, reacted in the mixture? b) How many grams of the K2C2O4XH2O in the salt mixture remain unreacted (in excess)?
