Alcohol with high concentrations can be obtained after double or triple distillation of some cereals grains or fruits.
It is prepared from a special denatured alcohol solution and contains approximately 70 percent by volume of pure, concentrated ethanol (ethyl alcohol) or isopropanol (isopropyl alcohol), so approximately 35 mL in a 50mL bottle.
For ethyl alcohol (ethanol) to be considered a general-purpose disinfectant, it typically needs to have an alcohol content of at least 60% to 90%. Isopropyl alcohol (isopropanol) also requires a similar concentration, generally ranging from 70% to 91% alcohol content, to effectively kill a broad range of pathogens. Lower concentrations may not be as effective in achieving disinfection.
No. The chemical structure of ethyl alcohol gas is the same as ethyl alcohol liquid.
To prepare 100ml of 70% Ethanol, measure 70ml of 95% ethyl alcohol in a graduated cylinder and add 30ml of distilled water. To prepare 100ml of 70% Ethanol, measure 70ml of 95% ethyl alcohol in a graduated cylinder and add 30ml of distilled water.

70% alcohol signifies the amount the alcohol present in 100 ml of the solution. Considering the solvent to be water, 70% alcohol contains 70ml alcohol and 30ml water. Thus, the total comes out to 70 + 30 = 100ml. That's what the "%" signifies - (out of 100!)
684 ml
I personally just put some 65% ethyl alcohol hand sanitizer on mine, and it burnt really bad for a minute or two. 70% probably won't kill you. Feelin' so fresh!

2/3 of 70% and 1/3 of 10%
Wieland said Lysol disinfectant spray contains about 80 percent ethyl alcohol, compared with 40 percent to 50 percent in most whiskeys.

95 ml of ethyl alcohol to 5 ml of water
Because the concentration of alcohol is lower; you pay the alcohol not the water.
