Calculate the amount of heat required to completely sublime 24.0 g of solid dry ice CO_2 at its sublimation temperature. The heat of sublimation for carbon dioxide is 32.3 kJ/mol.

  • chemistry -

    32.3 kJ/mol x mols CO2 = q (heat required).
    How many mols CO2 are in 24.0 g CO2? Something like 24.0/molar mass CO2?
    Check my thinking.

  • chemistry -

    24g CO2 x (1mol/44.01g) x (32.3 kj/1mole) = 17.6 kj
