What is the molality of a solution that has 4 mol of KCl in 0.800 kg of water?A.B.C.D.
Question
Solution 1
Molality (m) is defined as the number of moles of solute per kilogram of solvent. It is expressed in moles/kg.
Given: Number of moles of KCl (solute) = 4 mol Mass of water (solvent) = 0.800 kg
We can use the formula for molality:
m = moles of solute / mass of solvent in kg
