How do you dilute 95% alcohol to 75 %?

All we have to do is to subtract the volume of 95% alcohol from the volume of 75% alcohol, in this case: 1.26 x 1.00 = 0.26 l = 260 ml.

This means that you have 75% of pure alcohol and 25% of water:

  1. 0.75 x 1000 = 750 ml.
  2. This is the amount of pure alcohol.
  3. 0.25 x 1000 = 250 ml.
  4. This is the amount of water.
