The two factors must be considered when predicting whether two substances will dissolve in each other are type of bonds and size of the molecules are two factors.
<h3>What is solubility?</h3>
Solubility is the ability of solute particles to dissolve in any solvent, and solubility is directly proportional to the dissolving ability of the solute.
Solubility of any substance depends on the type of the bond present in the solute molecule i.e. polar or non polar. And it is also depends on the size of the solute as size defines the surface tenssion of the substance.
- Number of bonds and shape of molecules are also define the solubility but not at that extent as their type and shape.
Hence type of bonds and size of the molecules are two factors.

There are 3 significant figures in the number 0.00666. They are each of the non-zero number 6's. The zero's before a number are not significant. The zeroes AFTER a number ARE significant.
For example:
0.006660 has four significant figures because there is a zero after nonzeroes.
0.00666 only has three significant figures because the zeros before a significant figure are not significant.
Any Questions?
The yellow coloring is a polar substance hence it dissolve in water. Blue dye is nonpolar hence it dissolves in less polar acetone.
In chemistry, there is a general rule that like dissolves like. A substance can only dissolve in another if there is some kind of intermolecular interaction between the substances.
The yellow food coloring is a polar substance hence it is able to dissolve in water which is a polar solvent. The blue dye is a nonpolar substance hence it dissolve in acetone which is a less polar solvent.
