The units of parts per million (ppm) and parts per billion (ppb) are commonly used by environmental chemists. In general, 1 ppm means 1 part of solute for every 106 parts of solution. Mathematically, by mass: ppm=gsolutegsolution=mgsolutekgsolution In the case of very dilute aqueous solutions, a concentration of 1.0 ppm is equal to 1.0 g of solute per 1.0 mL, which equals 1.0 g solution. Parts per billion is defined in a similar fashion. Calculate the molarity of each of the following aqueous solutions. a. 5.0 ppb Hg in H2O b. 1.0 ppb CHCl3 in H2O c. 10.0 ppm As in H2O d. 0.10 ppm DDT (C14H9Cl5) in H2O
In an accident, a solution containing 2.5 kg of nitric acid was spilled. Two kilograms of Na2CO3 was quickly spread on the area and CO2 was released by the reaction. Was sufficient Na2CO3 used to neutralize all of the acid?
What mass of HCl is contained in 45.0 mL of an aqueous HCl solution that has a density of 1.19 g cm-3 and contains 37.21% HCl by mass?
A solution is 0.1% by mass calcium chloride. Therefore, 100. g of the solution contains g of calcium chloride.
(For Exercises 4546) Solutions containing nickel(II) ion are usually bright green in color. When potassium hydroxide is added to such a nickel(II) solution, a pale-green fluffy solid forms and settles out of the solution. The fact that a reaction takes place when potassium hydroxide is added to a solution of nickel(II) ions is an example of a properly. . The fact that a solution of nickel(II) ion is bright green is an example of a property.
A throat spray is 1.40% by mass phenol, C6H5OH, in water. If the solution has a density of 0.9956 g/mL, calculate the molarity of the solution.
A newspaper article about the danger of global warmingfrom the accumulation of greenhouse gases such as carbondioxide states that “reducing driving your car by 20 milesa week would prevent release of over 1000 pounds of CO2 per year into the atmosphere.” Is this a reasonable statement?Assume that gasoline is octane (molecularFormula C8H18 ) and that it is burned completely to CO2 and H2O in the engine of your car. Facts (or reasonable guesses)about your car’s gas mileage, the density of octane, andother factors will also be needed.
How do we define the mass percent composition of a solution? Give an example of a solution, and explain the relative amounts of solute and solvent present in the solution in terms of the mass percent composition.
