## What is Molality formula?

Formulas Needed for Problem Solving The unit of molality is, therefore, expressed in moles per kilogram.

The formula for molality is m = moles of solute / kilograms of solvent..

## What is the molality of a solution which contains 36 g of glucose in 250g of water?

=(36g)(180 g mol-1)×(0.25kg)=0.8mol kg-1=0.8m.

## When 10g of Naoh is dissolved in 500g of water calculate the molality of the solution?

1 Answer. Ernest Z. The molality is 0.50 mol/kg.

## What is the molality of glucose?

1 Answer. The molality is 1.42 mol/kg, or 1.42 m. Molality, m, is the moles of solute divided by the mass in kg of solvent.

## What will be the molality of a solution of glucose in water which is 10 weight by weight?

10% by weight solution of glucose means in 100 g of solution there are 10 g of glucose and 90 g of water. The molality of the solution is 0.6172 mol/kg.
