## Homework Statement

The standard enthalpy of sublimation of dry ice (solid carbon dioxide) is 6.03 kJ/mol.

The triple point of CO2 is at 5.1 atm, -59.7 °C.

Calculate the normal sublimation temperature of CO2 at 1.00 atm pressure.

## Homework Equations

Delta G= Delta H-T(delta S)

## The Attempt at a Solution

I know delta G will be zero and and that delta H will be the same as the standard Enthalpy. I imagime I need to calculate delta entropy for sublimation at 1 atm but I have no idea how.
