Question

Back in the 1980’s when a college student wanted an extra boost of caffeine, they drank some
Mountain Dew which has 36 mg of caffeine in 8.0 fluid ounces of soda (as compared to Coke or
Pepsi which have about 23-25 mg caffeine).

How many nitrogen atoms are there in the caffeine in 3 bottles of Mountain Dew if each bottle
contains 2.0 liters of soda?

a. Write the conversion equations for the conversions provided in the problem and for any mole
tools needed – there should be 5 conversion equations in total. Note: For a conversion
equation, it is acceptable for the numbers on both sides of the equation to be something other
than 1.

b. Use the method of dimensional analysis to solve the problem starting with the number in the
problem that is not a conversion.

Note: For this problem, every number in the conversion equations for part (a) and in the conversion
fractions for part (b) should include a unit and a substance.
