To calculate the number of standard drinks we use the formula $N=0.789\times V\times A$N=0.789×V×A; where
$V$V is the volume of the drink in litres (L); and
$A$A is the percentage of alcohol (% alc/vol) in the drink.
Calculate the number of standard drinks in a $375$375 mL bottle of mid strength beer that has an alcohol content of $3.5%$3.5% alc/vol to the nearest one decimal place.
