What volume of ethyl alcohol is contained in 35 mL 86 proof liquor which 43 percent?

To calculate the volume of ethyl alcohol in 35 mL of 86 proof liquor, we can use the following formula:

Volume of alcohol = Volume of liquor × Alcohol content percentage

Given that the liquor is 86 proof, its alcohol content percentage is 43% (since 100 proof is equal to 50% alcohol content, and 86 proof is 43% of that). Therefore, the alcohol content percentage is 0.43.

Substituting the given values into the formula, we get:

Volume of alcohol = 35 mL × 0.43

= 15.05 mL

Therefore, the volume of ethyl alcohol contained in 35 mL of 86 proof liquor is 15.05 mL.
