The molar heat of vaporization of carbon disulfide (CS2) is 28.4 kJ/mol at its nor- mal boiling point of 46◦C. How much energy (heat) is required to vaporize 5.4 g of CS2 at 46◦C?

First, you need to convert the mass to moles. Since CS2 is already at its boiling point then you can just proceed with the equation for heat using the heat of vaporization given. Don't forget to convert to the units required which Joules. enter image description here
