A student determines the decоmpоsitiоn of NаHCO3 (sodium bicаrbonаte). A student placed the sample of NaHCO3 in a crucible and heated to determine the moles of CO2 formed. The following data was recorded. The decomposition follows following reaction; 2NaHCO3 -----> Na2CO3 + H2O + CO2 What is the number of moles of bicarbonate heated? What is the number of moles of CO2 formed? Mass of empty crucible 25.2550 g Mass of crucible + sample 26.5050 g Mass of sample (calculate) ? Mass of crucible + sample after heating 26.0050 g Mass of decomposition product (calculate) ? Mass of carbon dioxide lost (calculate) ?
