An acid solution contains 18 kg of water and pure hydrochloric acid (HCl). Its

concentration is 0.60 mol/kg of solvent. Compute for the number of moles of solute contained in the solution

Answer 1

Molality = moles of solute / mass (in kg) of solvent

n(HCl) = C_m(HCl) * m(H₂O) = 0.60 mol/kg * 18 kg = 10.8 moles
