1. A tanker truck containing 6 tonnes of gasoline spills.into a nearby lake. The lake is 40 meters deep,
200 meters wide, and 700 meters long (average dimensions). What would be the resulting average
concentration of gasoline in the lake, in milligrams per liter and grams per cubic meter?
Notes:
1 tonne = 1,000 kilograms = 1,000,000 grams
Volume = length x width x depth
Concentration = weight/volume
