Question

When the products released by explosion of 0.04 mole of nitroglycerine were placed in a 821 ml flask and the flask was cooled to –23°C, product 'A' solidified and the pressure inside the flask was 4.75 atm. How many moles of A were present and what is its likely identity? Neglect the volume of solid formed.

Prashant Kotian · Accepted Answer

Correct answer: C. Remaining gases at 250 K: . Total gases initially = 0.29 mol. Solid A = . Solidifies at -23°C, so it is H₂O. Therefore, correct answer is C.
