when heated, sodium bicarbonate, NaHCO3, decomposes into sodium carbonate, Na2CO3, water, and carbon dioxide. If 5.00 g of NaHCO3 decomposes what is the mass of the carbon dioxide produced?

    Write and balance the equation.
    2NaHCO3 ==> Na2CO3 + 2CO2 + H2O
    Check my balancing.

    Convert 5.00 g NaHCO3 to moles. moles = grams/molar mass.

    Using the coefficients in the balanced equation, convert moles NaHCO3 to moles CO2.

    Now convert moles CO2 to grams. g = moles x molar mass
