In order for a solute to dissolve in a solvent,
the attractive forces between solute particles and the solvent particles must
be stronger than the attractive forces between solute-solute and
solvent-solvent particles. This is important so that the solute will remain in
solution.
To Earth, since it has the same radio and masses. This is what I believe.
Hope you understand how to work out those types of questions now xD ;)
