Question

A careless fisherman accidentally spilled an entire 20-oz bottle of soda into Lake Michigan. The soda contained 101.8 mg of caffeine (c8h10n4o2) per 20 oz bottle. What is the resulting molar concentration of caffeine in the lake? Assume that the lake receives no additional caffeine other than from this one bottle of soda; you may also assume that the caffeine is evenly distributed throughout the lake.

Useful facts about Lake Michigan:

Surface area= 5.80 x 10^4 km^2

Average depth = 279 ft

Average water density = 1.0 g/mL
