A 0.4020 g sample was dissolved, and Ca2+ and Ba2+ ions present were precipitated as Ba.C2O4.H2O and CaC2O4H2O. The Oxalates were then heated in a thermogravimetric apparatus leaving a residue that weighed 0.3175 g in the range of 320°C to 440°C and 0.2165 g in the range of 580°C to 620°C. Calculate percentage Ca and percentage Ba in the sample.
