to determine the freezing point depression of a licl solution, toni dissolved 0.393 g of licl in 20.3 ml of distilled water. determine the molal concentration (m) of the resulting solution. mwlicl



Answer :

The molal concentration of the resulting solution is 0.453 m.

Molal concentration is the measure of the concentration number of moles of solute in 1 kg of solvent.

To calculate the molal concentration -

Calculate the mass of LiCl -

mass = density x volme

mass = 1 g/mL x  20.3 mL

mass = 20.3 g  

mass = 0.0203 kg

Calculate the moles of LiCl:

Number of moles = Given mass

                                 Molar mass

                          n =    0.393 g       = 9.2 x 10⁻³ mol

                                 42.394 g/mol

So, the molal concentration is,

M = 9.2 x 10⁻³ mol

      0.0203 kg

M = 0.453  m

Therefore, the molal concentration of the resulting solution is 0.453 m.
