5. Gas stoichiometry
(Points: 1) 
     One process related to formation of smog is:
2NO(g) + O2(g) 2NO2(g)
This reaction can be monitored in the laboratory by finding the total pressure of a mixture of the gases.

A bulb of volume 1.000 L is filled with a mixture of NO(g) and O2(g). The initial total pressure is 335 kPa at 26.4°C. After 6 hours the total pressure is 263 kPa. What mass of NO2(g) in grams has been formed? Answer to 2 decimal places, do not include units.
