Question

If molality of NaOH in an aqueous solution is
8 m and the density of the solution is 1.5 g mL-1
then the molarity of NaOH solution will be​

Answer 1

Answer:

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
