Depends on what "parting" refers to.

If the cloud was destroyed, you'd take how much water there is and calculate how much energy it takes to vaporize it. (2264709 J/KG of water)

If it was split in two, you'd have to get how fast the pieces are moving and use KE to calculate. (KE = 0.5*Mass*Speed^2)

This page has information on that stuff
