- A martini, weighing about 5.0 oz (142 g), contains 30.0% by mass of alcohol. About 15% of the alcohol in the martini passes directly into the bloodstream (7.0 L for an adult). Estimate the concentration of alcohol in the blood (g/cm3) of a person who drinks two martinis before dinner. (A concentration of 0.00080 g/cm3 or more is frequently considered indicative of intoxication in a normal adult.)Silver ions can be found in some of the city water piped into homes. The average concentration of silver ions in city water is 0.028 ppm. (a) How many milligrams of silver ions would you ingest daily if you drank eight glasses (eight oz/glass) of city water daily? (b) How many liters of city water are required to recover 1.00 g of silver chemically?4. Predict the effect of temperature decrease, (b) pressure increase, (c) concentration increase of O2 on the concentration of all species. Answer using "more" or "less". 2 SO3(9) O2(9) + 2 SO2(9) AH = - 47 Kcal a. b. С.
