Calculate the molarity and molality of a 48.0 wt% hydrofluotic acid, if the density of the hydrofluoric acid is 2.4 g/mL The environmental protection agency (EPA) has set standard levels for the amount of metal ion contaminants in drinking water. The upper limit for lead (Pb) is 1.5 part million. Common sources of lead are corrosion of household plumbing and erosion of natural deposits. Suppose a city found 1.8 nanogram of Pb in 1 gram of water of its drinking water supply. What is the concentration (in ppb) of Pb in the water sample? From your calculation above, is this water safe for human consumption?
