I'm sure this will look familiar after you see it.
You remember the heat to raise the temperature of ice from -50 to steam at 300 C. This is done the same way.
q1 = heat to vaporize liquid SO2 at it boiling point.
q1 = mass liquid SO2 x heat vaporization.
q2 = heat to move vapor SO2 from its boiling point to 60 C.
q2 = mass vapor SO2 x specific heat SO2 gas x (Tfinal-Tinitial)
Total heat = q1 + q2
Watch the units. I would keep everything in grams and joules, then convert to the unit I wanted at the end after adding q1 and q2.
