80 proof brandy is 40.0% (v/v) ethyl alcohol

 

 

An 80 proof brandy is 40.0% (v/v) ethyl alcohol.

The “proof” is twice the percent concentration of alcohol in the beverage.

How many milliliters of alcohol are present in 780 mL of brandy?

 

---------------------------------------------------

 

40.0% (v/v) = 40.0 mL 에탄올 / 100 mL 브랜디

 

 

780 mL 브랜디 × (40.0/100) = 312 mL 에탄올

( 참고 https://ywpop.tistory.com/9293 )
