if 21.54 grams of caco3 is added to an ecxess of HCl in the equation Cacl3+2Hcl produces Cacl3+co2+H20, what mass does co2 produce?

  • chemistry -

    You have two typos in your equation. The correct equation, balanced, is
    CaCO3 + 2HCl ==> CaCl2 + H2O + CO2
    mols CaCO3 = grams/molar mass
    mols CO2 = mols CaCO3 from the coefficients in the balanced equation.
    Now g CO2 = mols CO2 x molar mass CO2.
