QUES A certain compound was known to contain calcium and chlorine. A sample that weighed 2.78g was dissolved in water, and excess sodium oxalate solution was added to precipitate all the calcium as calcium oxalate, CaC204. The equation for this reaction was: Ca* (aq)+ C,0, (ag)→ CaC,0,(s) The precipitate was then collected by filtration and heated strongly so that calcium oxide, CaO, formed. The calcium oxide was found to have a mass of 1.40 g. What was the empirical formula of the compound?

QUESTION 5 A certain compound was known to contain calcium and chlorine. A sample that weighed 2.78g was dissolved in water, and excess sodium oxalate solution was added to precipitate all the calcium as calcium oxalate, CaC204. The equation for this reaction was: Ca** (aq)+ C,0, (ag)→ CaC,O,(s) 2- The precipitate was then collected by filtration and heated strongly so that calcium oxide, CaO, formed. The calcium oxide was found to have a mass of 1.40 g. What was the empirical formula of the compound?
