Answer:
Molality = 0.33 mol/Kg
Explanation:
Given data:
Volume of solvent = 2.00 L
Mass of solute = 225 g
Molality of solution = ?
Solution:
Formula:
Molality = Number of moles of solute / kg of solvent
Now we will calculate the moles of solute.
Number of moles = mass/ molar mass
Number of moles = 225 g/ 342.3 g/mol
Number of moles = 0.66 mol
Now we will calculate the Kg of solvent.
1 L = 1 Kg
2 L = 2 Kg
Molality = Number of moles of solute / kg of solvent
Molality = 0.66 mol / 2 kg
Molality = 0.33 mol/Kg
