The Burke Museum at the UW is analyzing a dinosaur bone sample for the amount of calcium it contains. The bone sample was dissolved in hydrochloric acid, giving 50.0 mL of solution containing calcium chloride. To precipitate the calcium ion from the resulting solution, an excess of potassium oxalate was added. The resulting precipitate of calcium oxalate, CaC2O4, weighed 1.437 g. What was the molarity of CaCl2 in the solution?
