The heat of vaporization of carbon tetrachloride (CCl4) is 197.8 J/g. How much energy is absorbed by 1.35 mol CCl4 when it vaporizes at its boiling point?

Respuesta :

Energy absorbed from changing the phase of a substance from the liquid phase to gas phase can be calculated by using the specific latent heat of vaporization. Calculation are as follows:

 

 Energy = 1.35 mol  CCl4 ( 153.81 g / 1 mol ) x 197.8 J/g 

 

Energy = 41071.88 J

The correct answer would be - 41.1 kj
