How many moles of HCl are in 15.0 mL of a 1.37 M solution of aqueous solution of HCl?

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

.
