How can solutions be different?

By composition, and by concentration...

Explanation:

Clearly, we can prepare solutions of different solutes, and with DIFFERENT SOLVENTS...we are not forced to use water as a solvent, and many solutes would not be water-soluble. And of course, given some degree of solubility in the solvent, we could prepare solutions of different concentration, i.e. a different amount of solute per volume of solution...

Typically, solution concentration is reported as a #"molarity..."#

#"Molarity"="Moles of solute"/"Volume of solution"#.

#"Molality"# can also be used, and is preferred in some circumstance...

#"Molality"="Moles of solute"/"Kilograms of solvent"#.
