How much pure alcohol in a 5 once glass of wine?

The amount of pure alcohol in a 5-ounce glass of wine depends on the wine's alcohol by volume (ABV) percentage. For example, if the wine has an ABV of 12%, it would contain about 0.6 ounces of pure alcohol (5 ounces x 0.12 = 0.6 ounces). If the ABV is higher or lower, the amount of pure alcohol would adjust accordingly.
