# A student analyzes a 2.00 g mixture of sodium bicarbonate (NaHCO,, molar mass = 84 g/mol) and sodium chloride (NaCl,
molar mass = 58.5 g/mol) by heating the mixture. The reaction below occurs.
2 NaHCO3(s) - Na, CO,(s) + H2O(g) + CO2(g)
She thoroughly heats the test tube to ensure a complete reaction. The solid (molar mass 106 g mol-') weighs 1.06 g after
heating. Based on the data, what was the percent of sodium bicarbonate in the original 2.00 g sample of the mixture?
