Question

 An empty 3.00 L bottle weighs 1.70 kg. Filled with wine it weighs 4.55 kg. The wine contains 11.0% ethyl alcohol by mass. How many ounces of ethyl alcohol are present in a 400.0 mL glass of wine? (1 lb = 16 oz = 453.6 g)

Answer 1

4.55 kg - 1.70 kg = 2.85 kg or 285 grams

 

285 * .11 = 31.35 grams of alcohol

 

That's the amount of alcohol in 3 liters of wine or 10.45 grams per liter.

 

400 mL is 40% of a liter = so the glass contains 4.18 grams of alcohol.

 

If 16 oz = 453.6 grams how many ounces is 4.18 grams?
