Please help me and show me step by step. assume that the reactions are being performed at pressure of 1.2 atm and a temperature of 298K
Calcium carbonate decomposes at a high temperature to form carbon dioxide and calcium oxide. How many grams of calcium carbonate will be nedded to form 3.45 L of carbon dioxide?

  • chemistry -

    1. Write the equation and balance it.
    CaCO3 ==> CO2 + CaO

    2. Use PV = nRT to calculate n = number of moles CO2. You know P, V, T, R.

    3. Using the coefficients in the balanced equation, convert moles CO2 to moles CaCO3.

    4. Now convert moles CaCOP3 to grams. g = moles x molar mass.
