The molality of the isopropyl alcohol in the solution is 13.95 m
<h3>Assumption</h3>
- Let the mass of the solution be 100 g.
- 45.6% by mass isopropyl alcohol = 45.6 g
- Mass of solvent = 100 – 45.6 = 54.4 g
<h3>Determination of the mole </h3>
- Mass of isopropyl alcohol = 45.6 g
- Molar mass of isopropyl alcohol = 60.11 g/mol
- Mole of isopropyl alcohol =?
Mole = mass / molar mass
Mole of isopropyl alcohol = 45.6 / 60.11
Mole of isopropyl alcohol = 0.759 mole
<h3>How to determine molality </h3>
- Mole of isopropyl alcohol = 0.759 mole
- Mass of solvent = 54.4 g = 54.4 / 1000 = 0.0544 Kg
Molality = mole / mass of solvent
Molality = 0.759 / 0.0544
Molality = 13.95 m
