Answer:
1.7 Osm/L
Explanation:
Osmotic concentration is the number of osmoles (Osm) of solute per litre of solution .
![\text{Osmotic concentration} = \dfrac{\text{No. of osmoles }}{\text{Litres of solution}}](https://tex.z-dn.net/?f=%5Ctext%7BOsmotic%20concentration%7D%20%3D%20%20%5Cdfrac%7B%5Ctext%7BNo.%20of%20osmoles%20%7D%7D%7B%5Ctext%7BLitres%20of%20solution%7D%7D)
An osmole is the number of moles of solute that contribute to the osmotic pressure of a solution.
1 Osm = i × n, where
i = the van't Hoff i factor and
n = the number of moles
The van't Hoff i factor is the number of solute particles obtained from 1 mol of solute.
For example,
MgSO₄(aq) ⟶ Mg²⁺(aq) + SO₄²⁻(aq)
1 mol of MgSO₄ produces 2 mol of ions in solution, so i = 2.
![\text{Osmotic concentration} = \dfrac{\text{1.0 Osm}}{\text{0.6 L}} = \textbf{1.7 Osmol/L}](https://tex.z-dn.net/?f=%5Ctext%7BOsmotic%20concentration%7D%20%3D%20%5Cdfrac%7B%5Ctext%7B1.0%20Osm%7D%7D%7B%5Ctext%7B0.6%20L%7D%7D%20%3D%20%5Ctextbf%7B1.7%20Osmol%2FL%7D)
To make diluted solutions from concentrated solutions, we can use the following formula,
C1V1 = C2V2
C1 is concentration and V1 is volume of concentrated solution taken to dilute the solution,
C2 is concentration and V2 is volume of diluted solution.
substituting values in the equation,
0.266 M x V = 0.075 M x 150.0 mL
V = 23.6 mL
therefore answer is 23.6 mL
