Question

Calculate the enthalpy change when 2.38 g of co vaporizes at its normal boiling point, if the enthalpy of vaporization of co is 6.04 kj/mol.

Answer 1

Answer : The enthalpy change is 0.5134 KJ.

Solution : Given,

Mass of carbon monoxide = 2.38 g

Enthalpy of vaporization = 6.04 KJ/mole

Molar mass of carbon monoxide = 28 g/mole

The enthalpy change when 28 g carbon monoxide vaporizes at normal boiling point = 6.04 KJ/mole

and The enthalpy change for 2.38 g of carbon monoxide vaporizes at normal boiling point =

Therefore, the enthalpy change is 0.514 K
