14% (that's v/v) means 14 cc ethanol/100 cc wine so
750 cc wine x (14 cc ethanol/100 cc wine) = about 105 cc ethanol.
14 units x (10 cc ethanol/unit) = 140 cc ethanol
140 cc ethanol x (1 bottle/105 cc ethanol) = ? bottles
750 cc wine x (14 cc ethanol/100 cc wine) = about 105 cc ethanol.
14 units x (10 cc ethanol/unit) = 140 cc ethanol
140 cc ethanol x (1 bottle/105 cc ethanol) = ? bottles
