A container of volume 2 . 24   L can with stand a maximum pressure of 2 atm at 298   K before exploding. The maximum amount of nitrogen (in g ) that can be safely put in this container at this temperature is closest to
Options
- A2 . 8
- B5 . 6
- C1 . 4
- D  4 . 2
Correct answer
D.   4 . 2
Step-by-step solution
From ideal gas equation p   V = n   R   T maximum number of moles in container, n = p V R T = 2 × 2 . 24 0 . 0821 × 298 = 0 . 18 moles Maximum weight of N 2 in container = 0183 × 28 = 5 . 127   g At 5 . 127   g exploding can occur. Thus, it must be less than 5 . 127   . Thus, the maximum amount of nitrogen that can be safely put in this container at 298 temperature and exert pressure less than 2   atm will be closest to undefined.
