What is the molality of a solution when 1.2 moles mgcl2 is stirred in 1000 grams of water?

The molality of the solution is 1.2 m.

Explanation:

To calculate the molality of the solution, we use the equation:

We are given:

Moles of (solute) = 1.2 moles

Mass of water (solvent) = 1000 g = 1 kg     (Conversion factor: 1 kg = 1000 g)

Putting values in above equation, we get:

Hence, the molality of the solution is 1.2 m
