What will be the molality of a 0.05M NaCl solution?

Answer» MOLARITY = No. of MOLES of solute / volume of SOLUTION

Given,

Molarity = 0.05M
Volume of Solution = 1L

no. of moles of solute = 0.05 mol

Take density of water = 1g/cm³

Then, mass of water = 1Kg

Molality = Moles of solute/Mass of solution

Molality = 0.05/1

Molality = 0.05

I'm not sure about this answer.
