Well, by definition, #"molarity"="moles of solute"/"volume of solution"#

Explanation:

Now the #"moles of solute"# are a constant. The volume of solution MAY change substantially with increasing or decreasing temperature. In some calculations #"molality"# is used in preference, which is defined by the quotient....

#"molality"="moles of solute"/"kilograms of solvent"#

....this is temperature independent, and at lower concentrations, #"molarity"-="molality"#.
