The molality of solution is 1.2 mole/kg

Explanation:

Molality of a solution is defined as the number of moles of solute dissolved per kg of the solvent.

where,

n = moles of solute

= weight of solvent in kg

Given : 10 g of glycerol is present in 100 g of solution

moles of glycerol =

mass of water (solvent )= (100-10) = 90 g = 0.09 kg

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

Therefore, the molality of solution is 1.2 mole/kg
