Neat Problems  [These may be bonus questions on the test!]

 1. Calculate the value of R in units of gallons•tons/acre             Try in units of  miles•ounces
                                                       molecule•Rankine                                  dozen•kelvin

 2. Air is approximately 78% N2, 21% O2, 0.9% Ar, 0.05% CO2, and 0.05% CH4.  What is the molecular
     weight of air?  What is the density of air at STP?  What is the partial pressure of CO2 in
     the atmosphere at STP?

 3. Look at the equation in "Chemistry at Work" on page 379.  Each stage of a uranium isotope separation increases the
     fraction of U-238 by a ratio of 1.0043:1. About how many stages would be required to increase the ratio to 100:1?
