Question

How many L of carbon dioxide gas will be produced from the decomposition of 5.0g of sodium hydrogen cardonate?
2NaHCO3 ==> Na2CO3 + CO2 + H2O

mols NaHCO3 to start = grams/molar mass.
Convert mols NaHCO3 to mols CO2 using the coefficients in the balanced equation.

Convert mols CO2 to L remembering that mols CO2 x 22.4 L/mol = L CO2.
