An analysis of zinc in a vitamin \& mineral "infused" water (with caffeine and taurine) was determined by a colorimetric analysis @ 556 nm after reaction with the compound 1-(2-pyridylazo)-2-naphthol. A 100.00 ppb zinc solution was used to prepare standards. A reagent blank had an absorbance of 0.0261@556nm. A 25.00mL sample of the "infused" water was combined with the other reagents and diluted to 100.00mL. This solution had an absorbance of 0.1234 What is the molar concentration of zinc in the "infused" water? The "infused" water is sold as a 10 ounce can. The FDA recommended daily amount of zinc is 11mg. How many mg of zinc are present in the entire can? What percent of the FDA amount is this
