In lab we vaporized a sample of acetone and measured the volume change of ice that was formed during the vaporization of the sample. This volume change was 0.29 mL. How do I calculate the heat of vaporization?

Other given data:

Heat of fusion of ice at O degees C = 79.71 cal/g

Volume change for ice to water at 0 degrees C = -0.0906 mL/g
