The molality of a solution : m = 2 mol/kg

Further explanation

Given

6 moles of NaOH

3 kg water

Required

The molality

Solution

Molality shows the number of moles dissolved in every 1000 grams of solvent( 1 kg solvent)

m = n. (1000 / p)

m = Molality

n = number of moles of solute

p = Solvent mass (gram)

Input the value :

m = 6 moles : 3 kg

m = 2 mol/kg
