#J//kg#

Explanation:

Latent heat is the amount of energy required to change the phase of 1 kg of a material and hence the unit is Joules per Kilogram.

In particular, specific latent heat of fusion is the amount of heat required to change phase of 1 kg between solid and liquid. #W=mL_f#

Specific latent heat of vapourization is the energy required to change phase of 1kg between liquid and gas. #W=mL_v#
