Question

14.6 to 5 gram of sodium chloride is dissolved in water find molality of solution

Answer 1

Explanation:

so moles NaCl = 70.128 g / (58.44 g/mol) = 1.2 mol . Plug moles value and the mass of the solvent into the molality formula. Divide 1.2 mol by 1.5 kg, and you'll find out that the molality of the NaCl solution is 0.8 molal (in standard molality units: 0.8 mol/kg).
