experiment was done to determine the composition of a mixture of sodium chloride and sodium carbonate. A sample of the mixture with a mass of 5.66 grams was heated until gas production stopped. After the reaction, the sample had a mass of 4.14 grams. Assuming that sodium chloride does not react and that the decrease in mass was due to the creation of CO2 gas, what wass the mass of Na2CO3 in the sample? Report your answer with three significant figures.

Question
Metal carbonates decompose to form metal oxides and carbon dioxide. An experiment was done to determine the composition of a mixture of sodium chloride and sodium carbonate. A sample of the mixture with a mass of 5.66 grams was heated until gas production stopped. After the reaction, the sample had a mass of 4.14 grams. Assuming that sodium chloride does not react and that the decrease in mass was due to the creation of CO2 gas, what wass the mass of Na2CO3 in the sample? Report your answer with three significant figures.
Na2CO3 → Na2O + CO2
