Need moles sodium hydroxide first.

80 grams NaOH (1 mole NaOH/39.998 grams) = 2.000 moles NaOH

Molarity = moles of solute/Liters of solution

Molality = 2.000 moles NaOH/1 liter

= 2 M NaOH solution

M = moles of solute / kilograms of solvent.

Number of moles: 4

Weight of solvent in kg: (l and kg and same) 2

4/2=2
