Answer:
Molality = 0.267 mol/Kg
Explanation:
Given data:
Moles of KCl = 0.4 mol
Mass of solvent = 1500 g
Molality of solution = ?
Solution:
Formula:
Molality = moles of solute / kg of solvent
Now we will convert the g into kg.
1500 g× 1kg/ 1000 g
1.5 kg
Now we will put the values in formula.
Molality = 0.4 mol/ 1.5 kg
Molality = 0.267 mol/Kg
