Step 1

Molality is the way to express the concentration of any solution. It can be defined as the number of moles of solute dissolves in 1 kg of the solvent. The mathematical expression for molality can be written as:

Step 2

8 m solution or 8 molal solution of NaCl means 8 moles of NaCl dissolve in 1 kg of solvent. Calculate the mass of NaCl from the given moles and molar mass: help_outlineImage TranscriptioncloseMoles of NaCl 8 moles Molar mass of NaCl = 58.44 g/mol Mass of NaCl Moles x molar mass -8 moles x 58.44 g/mol = 467.5 g fullscreen
