7. Another nasty nitrogen compound formed during various reactions is NO2, a reddist brown gas, toxic and reactive as is typical for nitrogen oxides. Using the Van der Waa equation, calculate the pressure, in atm, of 100.0g of NO2 at 298K in a 5.00L vessel Van der Walls constants for NO2 are a=5.354L2atm/mol2 and 0.04424L/mol).(4 points)
