A flask is filled with 3.0 atm of N2 and 4.0 atm of O2. The gases react and NO2 is formed. What is the pressure in the flask after the reaction occurs as completely as possible? Assume that the volume and temperature in the flask remain constant.

(1) 4.0 atm (2) 5.0 atm (3) 6.0 atm (4) 8.0 atm (5) 10.0 atm

I keep getting 6atm but the answer is 5atm
