Math problem: calculating concentration
OK math whizzes: what is a microgram of mercury? Let's sort this out:
How many micrograms in a gram?
How many micrograms are there in, say a typical mercury thermometer?
An average thermometer contains 1 gram of mercury (note: Maine has tried to get mercury thermometers out of circulation; new ones contain alcohol instead).
If you broke a mercury thermometer in a lake that was 50 feet deep, 100 feet diameter, and perfectly round (and hemispherical), and if 1 cubic centimeter of water = 1 milliliter, what would be the concentration of mercury in the lake, in micrograms per liter?
