Calculate the amount of heat required to completely sublime 63.0 g of solid dry ice CO2 at its sublimation temperature. The heat of sublimation for carbon dioxide is 32.3 C.

  • Science -

    heat= heatsublimation*mass

    I am not certain what your units are on the heat of sublimation, but they need to be in Joules/gram.

  • Science -

    Convert grams to moles. (85)/(12+16+16)=1.93182

    1.93182*32.3=62.3977
