Chapter 1, Problem 1.86E

The estimated amount of recoverable oil from the field at Prudhoc Bay in Alaska is 1.3 1010 barrels. What is this amount of oil in cubic meters? One barrel = 42 gal (exact), 1 gal = 4 qt (exact), and 1 qt = 9.46 104 m3.

One year of world production of gold was 49.6 106 troy ounces. One troy ounce equals 31.10 g. What was the world production of gold in metric tons (106 g) for that year?

Potassium sulfate has a solubility of 15 g/ 100 g water at 40C. A solution is prepared by adding 39.0 g of potassium sulfate to 225 g of water, carefully heating the solution, and cooling it to 40C. A homogeneous solution is obtained. Is this solution saturated, unsaturated, or supersaturated? The beaker is shaken, and precipitation occurs. How many grams of potassium sulfate would you expect to crystallize out?

Convert the following Celsius temperatures to Kelvin and to Fahrenheit degrees. a. the temperature of someone with a fever, 39.2C b. a cold wintery day, 25C c. the lowest possible temperature, 273C d. the melting-point temperature of sodium chloride, 801C

An industrial waste lagoon is contaminated with cadmium. The concentration of Cd2+ in the lagoon is 1.2 mg/L. Convert this unit to μmol/L (remember your prefixes).

What volume of concentrated HCl (37.2% HCl m/m) contains 125 g HCl? The density of concentrated HCl is 1.19 g/mL.

part a) A student measured the mass of an empty micropicnometer to be 2.000g. A student places 0.500mL of citric acid solution into a micropicnometer. The student reweighed the micropicnometer and found the mass of the citric acid solution and micropicnometer to be 2.525g.  Calculate the density of the citric acid solution in g/ml. part b) A student measured the mass of an empty micropicnometer to be 2.000g. A student places 0.500mL of citric acid solution into a micropicnometer. The student reweighed the micropicnometer and found the mass of the citric acid solution and micropicnometer to be 2.525g.    A student titrates 0.101mL of citric acid solution using the standardized 0.1M solution (use the exact concentration calculated from the previous titration problem). The sample required 0.819mL of NaOH solution to reach the end point.   Given the following chemical equation.   NaOH   +  H3C6H5O7 →  Na+ +   H2O  +   C6H5O73-   Given the above information. Calculate the mass of citric…

A student pipetted 10 mL of a sample solution into a 250 mL volumetric flask and diluted it to the mark with distilled water. The student then, pipetted 10 mL of this new solution into a 50.00 mL volumetric flask and diluted it to the mark with water. What is the dilution factor of the final solution? 100X 25X 125X 5X 50X

You are a pharmacist at a drug store and a woman approaches you frantically, holding a bottle of Children's Advil. Her daughter has a fever and the company changed it's formulation. Now, she doesn't know how much medicine to give her daughter. With the old formulation, she gave 1.875 mL dosage that contained 50 mg of ibuprofen per 1.25 mL. The new formula contains 100 mg of ibuprofen per 5 mL. How many mL of medicine should the woman give her daughter?
