What is Gravimetric Analysis of Chloride and Calcium about?

A 0.5662 gram sample containing chloride ions reacted with silver nitrate, forming 1.0882 grams of silver chloride precipitate. This was used to calculate the percent by mass of chloride in the original compound as 47.51%. Additionally, calcium in a 200ml water sample was precipitated as calcium oxalate, with the ignited precipitate and crucible weighing 26.7134 grams. Subtracting the empty crucible mass yielded the calcium oxide mass, from which the calcium concentration in the water was calculated as 0.04
