The molality of a solid solution containing 867 g of aluminum and 14.9 g of copper is 0.27 mol/kg.

What is the molality of a solution?

The molality of a solution is a way to express the concentration of the solute in a given mass of solvent.

Molality of solution is given by the formula given below:

  • Molality = moles of solute/kilogram of solvent

In the given solid solution, aluminium is the solvent while copper is the solute.

Mass of solvent = 867 g = 0.867 Kg

Moles of solute = mass/molar mass

molar mass of copper = 64.0 g

moles of solute = 14.9/64 = 0.233 moles

Molality of solution = 0.233 mol/0.867 kg = 0.27 mol/kg.

Therefore, the molality of a solid solution containing 867 g of aluminum and 14.9 g of copper is 0.27 mol/kg.
