Question

a solution has been prepared by mixing 5.6ml of water. calculate the % (by volume)of alcohol in the solution

Answer 1

Answer:

80.6ml&6.9%

Explanation:

Volume of the alcohol = 5.6 ml = V1

And volume of water = 75 ml = V2

Total volume of solution = 5.6+75 = 80.6 ml.

Percentage of alcohol in the solution

= (V1 / volume of the solution) x 100% = (5.6/80.6) x 100 = 6.9 %
