The last one is the suns energy
Density (p) = Mass / volume
P=295/15.625
=18.88
therefore p=18.88
Answer:An ion-dipole force is a force between an ion and a polar molecule. A hydrogen bond is a dipole-dipole force and is an attraction between a slightly positive hydrogen on one molecule and a slightly negative atom on another molecule.
Hope it helps ;)
