A 600.0 mg sample consist only of CaC2O4 and MgC2O4 was heated at 500°C converting the two salts to CaCO3 and MgCO3. The resulting precipitate weighed 465.0 mg. If the sample had been heated at 900°C, the products would be CaO and MgO, what would the mixture of oxides weigh? (FW: CaC2O4=128.1; MgC2O4=112.3; CaCO3=100.1; MgCO3=84.31; CaO=56.08; MgO=40.31)

Question
A 600.0 mg sample consist only of CaC2O4 and MgC2O4 was heated at 500°C
converting the two salts to CaCO3 and MgCO3. The resulting precipitate weighed
465.0 mg. If the sample had been heated at 900°C, the products would be CaO
and MgO, what would the mixture of oxides weigh? (FW: CaC2O4=128.1;
MgC2O4=112.3; CaCO3=100.1; MgCO3=84.31; CaO=56.08; MgO=40.31)
