Anestetic [448]3 years ago
3 0
We can find out concentration of solution by dividing number of moles by volume.
Most concentrated solution is the solution with highest number of moles in a unit volume
Concentration = number of moles/ volume
1. 0.1 mol/ 0.4 L = 0.25 mol/L
2. 0.2 mol / 0.3 L = 0.67 mol/L
3. 0.3 mol / 0.2 L = 1.5 mol/L
4. 0.4 mol/ 0.1 L = 4.0 mol/L

From the given solutions most concentrated solution is 4th solution. In this the highest amount of solute dissolved in a unit volume is 4.0 mol. Therefore this is the most concentrated solution.
