A mom is concerned about fluoridation in drinking water. She has read that the maximum contaminant concentration level goal for fluoride in drinking water is 4 ppm. The mom has discovered that her drinking water supply contains 0.8 ppm of sodium fluoride. How many milligrams of sodium fluoride are contained in one liter of drinking water containing 0.8 ppm of sodium fluoride? What is the ratio strength concentration of sodium fluoride in drinking water that contains 0.8 ppm 1I. of...
Isopropyl alcohol is mixed with water to produce a 38.0% (v/v) alcohol solution. How many milliliters of each component are present in 875 mL of this solution? Assume that volumes are additive. alcohol: mL water: ml The mass of solute per 100 mL of solution is abbreviated as (m/v). Mass is not technically the same thing as weight, but the abbreviation (w/v) is also common. How many grams of sucrose are needed to make 695 mL of a 38.0% (w/v)...
