60% of alcohol solution means that, if 250 mL is the total volume of the solution, then
60% of 250 mL = (60*250) / 100 = 150 mL is alcohol
And, 250 mL - 150 mL = 100 mL is water.
Therefore 150 mL alcohol and 100 mL water should be mixed to, prepare 250 mL of 60% alcohol solution.
60% of 250 mL = (60*250) / 100 = 150 mL is alcohol
And, 250 mL - 150 mL = 100 mL is water.
Therefore 150 mL alcohol and 100 mL water should be mixed to, prepare 250 mL of 60% alcohol solution.
