Hi there, if anyone could please help explain this question to me or explain a simple method of how to do it so that I can use it in other questions similar that would be great!
) Whisky contains a higher concentration of ethanol.
(i) Before 1980, the concentration of alcohol in drinks was measured in terms of degrees proof. The concentration of alcohol in two drinks is shown in the table below, both as % abv and degrees proof.
Sample Alcohol concentration/%abv Alcohol Concentration/degrees proof
Wine 14.0 24.5
Sherry 20.0 35.0
A cask strength whisky has an alcohol concentration of 65% abv. Calculate the alcohol concentration of this whisky in degrees proof. (1)
