Question

What is the molality of a solution made by dissolving 2 moles of NaOH in 10
kg of water?

Answer 1

0.2mol/kg

Step-by-step explanation:

molality is the concentration of a solution in moles of solute per kilogram of solvent

moles of solute (NaOH) = 2moles

mass of solvent in kg. =10kg

Therefore molality. = 2moles/10 kg

=0.2mol/kg
