Chapter 12, Problem 47E
Interpretation Introduction

Interpretation:

The concentration of mercury in the given sample of well water is to be calculated and the water sample is safe or unsafe for human consumption is to be predicted.

Concept Introduction:

Water gets polluted due to the presence of various biological and chemical contaminants. Biological contaminants include microorganisms such as Giardia, Legionella while chemical contaminants are mercury, lead, benzene, trichloroethylene etc. Both these render water unfit for consumption by human beings and animals, if the contaminant exceeds a certain limit, termed as Maximum Contaminant Limit.

The concentration of a contaminant is reported as the mass of contaminant (in milligrams) present in one liter of water.

It is known that 1000 mL = 1 L, hence conversion factor of mm to L is as:

1000mL1 L

Concentration of solute = Mass of soluteVolume of solution

Seawater has a concentration of 0.60 M NaCl. The acceptable amount of NaCl in drinking water is 9.0g/L. How much pure water should be added to 2.50 L of seawater for it to be safe for human consumption?
Use ppm and ppb concentration units. The EPA's secondary standards for contaminants that may cause cosmetic or aesthetic effects in drinking water suggest an upper limit of 0.200 mg/L for aluminum . If 2.38×104 liters of water in a storage tank contains 19.3 grams of Al, what is the contaminant level in ppm? in ppb? Is this level acceptable based on EPA guidelines? ppm ppb acceptable not acceptable
A student makes a diluted solution of caffeine by pipetting 6.0 mL of the stock caffeine solution into a test tube and dilutes it with 1.0 mL distilled water. If the concentration of the stock caffeine is 10. mg/mL, what would be the concentration of caffeine (in mg/mL) in the test tube?
