Hi Jenson,

To determine the number of liters of 70% alcohol you can make, first we need to determine how many liters of 100% alcohol we have.

1 gallon = 3.79 liters, therefore we have 3.79 L of 100% alcohol.

To prepare 1L of 70% alcohol, you will need 700 mL of 100% alcohol which will be diluted with 300 mL of water.

3.79 L / 0.700 L = 5.41

Therefore, from 1 gallon of 100% alcohol (or 3.79 Liters) you can make 5.41 Liters of 70% alcohol solution.

I hope this helps!
