Find the molality of the solution of 25 g of i2 in 125 g of ethanol, c2h5oh

Answer : The molality of the solution is, 0.788 mole/Kg

Solution : Given,

Mass of solute, = 25 g

Mass of solvent, = 125 g

Molar mass of solute, = 253.8 g/mole

Molality : It is defined as the number of moles of solute present in one kilogram of solvent.

Formula used :

Now put all the given values in this formula, we get the molality of the solution.

Therefore, the molality of the solution is, 0.788 mole/Kg
