Answer: The volume of solvent evaporated is 173.57 mL
Explanation:
[tex]\text{Molarity of the solution}=\frac{\text{Moles of solute}\times 1000}{\text{Volume of solution (in mL)}}[/tex] .....(1)
Molarity of solution = 0.275 M
Volume of solution = 230.0 mL
Putting values in equation 1, we get:
[tex]0.275M=\frac{\text{Moles of solution}\times 1000}{230.0}\\\\\text{Moles of solution}=\frac{0.275\times 230}{1000}=0.0632mol[/tex]
As, the moles of solution remains the same.
When solvent gets evaporated, the volume of the solution is calculated by using equation 1:
Moles of solution = 0.0632 moles
Molarity of the solution = 1.15 M
Putting values in equation 1, we get:
[tex]1.15=\frac{0.0632\times 1000}{\text{Volume of solution}}\\\\\text{Volume of solution}=\frac{0.0632\times 1000}{1.15}=56.43mL[/tex]
Volume of solution evaporated = (230.0 - 56.43) mL = 173.57 mL
Hence, the volume of solvent evaporated is 173.57 mL
