Question

3. 150 ml of aqueous solution of ethanol contains 12.5 mL of ethanol.
Calculate the concentration of the solution ​

Answer 1

Answer:

Explanation:

Volume of solvent = 150 ml.

Volume of solution = volume of solute + volume of solvent

                                = 25 ml +150 ml.

                               = 175 ml.

Volume by Volume percentage =    volume of solute  * 100

                                                      volume of solution

                                               = 25 *100

                                                     175

 

                                               = 14.28
