We have that the the molarity of methanol in the solution is mathematically given as

Morality=7.91mol/l

Question Parameters:

An <u>aqueous </u><em>solution </em>of methanol (MM = 32.04 g/mol)

A molality of 8.83 m and a density of 1.15 g/mL.

Generally the equation for the is mathematically given as

$Morality=\frac{moles of solute }{mass of the solvent}$

where

Mass of solution=(100+282.2)

Mass of solution=1289.9

Volume=1289.9/1.15

Volume=1.115L

Therefore

$Morality=\frac{moles of solute }{mass of the solvent}$

Morality=8.83/1.115

Morality=7.91mol/l
