You can put this solution on YOUR website! 400ml of solution contains 15% alchohol.how much alchohol to be added to make the solution to contain 32% alchohol?
----------------------
400 ml of 15% --> 60 ml of alcohol and 340 ml of water.
To make a solution that has the 340 ml of water a 32% mix, the 340 ml will be 68% of it.
340/68 = Total/100
Total volume = 500 ml
So 100 ml of alcohol must be added. (Don't drink any)
----------------
As a check:
The new mix has 160 ml of alcohol in 500 ml total, = 32%
