Expert Answer

Step 1

dHvap is called the heat of vaporization which is the amount of heat required to convert a substance completely into its vapor or gas form.

To solve this problem we will use Clasius Clapeyron equation,

ln(P2/P1) = dHvap/R [(1/T1) - (1/T2)]

Given in the problem,

P1 = 621 torr                              ...
