A 0.60 g sample consisting of only CaC2O4 and MgC2O4 is heated at 500 – InterviewSolution

1.	A 0.60 g sample consisting of only CaC2O4 and MgC2O4 is heated at 500 oC converting the two salts to CaCO3 and MgCO3. The sample then weight 0.465 g. If the sample had been heated to 900 oC, where the products are CaO and MgO, what would the mixtures of oxide have weighed (in grams)?Report your answer upto two decimal only.
Answer» A $0.60 g$ sample consisting of only $C a C_{2} O_{4}$ and $M g C_{2} O_{4}$ is heated at $500^{o} C$ converting the two salts to $C a C O_{3}$ and $M g C O_{3}$ . The sample then weight $0.465 g$ . If the sample had been heated to $900^{o} C$ , where the products are $C a O$ and $M g O$ , what would the mixtures of oxide have weighed (in grams)? Report your answer upto two decimal only.
