The general formula for a Group 1 metal carbonate is M2CO3.  A gas evolution reaction is performed on a measured amount of an unknown Group 1 metal carbonate to determine its identity. The sample, 3.946 grams, is reacted with excess hydrochloric acid to ensure that the carbonate in each metal carbonate is converted into CO2 and H2O. After the gas evolution reaction, the sample lost 2.141 grams due to the release of CO2 from the reaction. What is the identity of the unknown Group I metal carbonate?     lithium carbonate     sodium carbonate     magnesium carbonate     potassium carbonate     calcium carbonate

Stoichiometry

Stoichiometry is a chemical division that evaluates the quantitative content of the chemical process with the help of the reacting molecules or products taking part in the reaction. The term “stoicheion” in “Stoichiometry”, is an old Greek term for "element" whereas “metron” means "measure".
