  1. My answer is 3.799 g which would round to 3.80. The difference COULD be the conversion from kPa to atm. I used 101.325 and I used 28 for the molar mass CO.

  2. I believe that you are right due to the conversion difference and the fact that none of the other answer are even remotly close !!!
    Thanks DR BOB
