Answer:
Methanol is more soluble > LiCl > Br2(l) > O2(g)
Explanation:
Arrange the following compounds in order to increase water solubility:
O2 = nonpolar gas, MW(Molecular weight)= 32 g/mol
LiCl= ionic salt, dissociate in Li+ and Cl-ions Br2= nonpolar liquid;
MW= 319.4 g / molmethanol(CH3OH)= polar liquid, MW= 32 g/mol
Therefore, with this data: polar methanol comes then, remember that like dissolves like, so polar + polar will dissolve pretty good LiCl appetite. However keep in mind that it will have a "saturation" point, since then most salts will not be infinitely soluble, Br2(l); since it is a non-polar liquid, it will have low solubility, but since it is a halogen, it will have low solubility.
Methanol is more soluble > LiCl > Br2(l) > O2(g)
