Question

A vessel containing 1 g of oxygen at a pressure of 10 atm and a temperature of 47 °C. It is found that because of a leak, the pressure drops to 5/8th of its original value and the temperature falls 27 °C. Find the mass of oxygen that is leaked out.

(a) (1/3)g

(b) (1/2)g

(c) (3/4)g

(d) (2/3)g

Answer 1

Correct option (a)

Explanation:

The pressure, temperature and the number of of oxygen in the vessel change due to leak while the volume ** fixed. Hence using PV = nRT, we
