A sample of a gaseous compound of nitrogen and oxygen weighs 5.25 g and occupies a volume of 1.00 L at a pressure of 1.26 atm and temperature of -4.0 °C. Which of the following molecular formulas could be that of the compound? A. NO
B. NO2
C. N3O6
D. N2O4
E. N2O5

The answer is D. N2O4, can someone please explain how they get this answer.

Answer:             1.0  × 10⁻⁵ msolution:                     as we know ph is given as,                                    ph  = -log [h⁺]and,                                    [h⁺]  =  10^-ph    (1)putting value of ph in eq. 1,                                    [h⁺]  =  10⁻⁵                                    [h⁺]  =  1.0  × 10⁻⁵ m
