    Mass of Calcium Carbonate = 500 grams

    The required reaction would be:

    CaCl₂ + Na₂CO₃ → CaCO₃ + 2NaCl

    Number of moles of CaCO₃:

    Number of moles = given mass / molar mass

    Number of moles = 500 / 100              [molar mass of CaCO₃ = 100g/mol]

    Number of moles = 5 moles

    Using the power of stoichiometry!!!

    CaCl₂ + Na₂CO₃ → CaCO₃ + 2NaCl

    from the balanced reaction listed above, we can see that one mole of CaCl₂ and one mole of Na₂CO₃ produces one mole of CaCO₃

    Moles of CaCl₂ = Moles of Na₂CO₃ = Moles of CaCO₃

    we just solved for the number of moles of CaCO₃, which gives us

    Moles of CaCl₂ = Moles of Na₂CO₃ = 5 moles

    Hence, 5 moles of CaCl₂ and Na₂CO₃ each is required
