Step 1

Given information:

Mass of dry ice = 25.0 g

Heat of sublimation of dry ice ΔHsub = 32.3 kJ/mol

Step 2

The amount of heat (q) required can be expressed in terms of number of moles (n) and heat of sublimation (ΔHsub) for a given sublimation process. The mathematical expression for this is represented as follows: Step 3

First number of moles of dry ice will be calculated as follows: ...
