Question

a solution contains 25 ml of alcohol mixed with 150ml of water. find concentration of solution​

Answer 1

Given,

25 mL of Alcohol in 150 mL of water.

----------------------------------------------------------------------------------------------------------------

So, total volume of solution = 25 + 150 mL => 175 mL

Concentration (v/v) in % = (volume of solute)/(volume of solution)*100

=> 25/175 * 100 => 100/7 => 14.28 % (v/v)

=> Hence, the concentration of the solution is 14.28 % (v/v)
