If I have a can of Tennant's Super straight, in a glass it comes in at what it says on the can right, 9% vol and 4.5 units of alcohol.
Depends how strong the lemonade is - usually it adds around 0.2 units to an average pint. You can cancel out the additional alcohol with 25ml of mescal, or a quart of rum.
