A contair of volume `0.1m^(3)` is filled with nitrogen at a temperature of `47^(@)` C and a gauge pressure of `4.0xx10^(5)` Pa. After ome time, due to leakage, the gauge pressure drops to `3.0xx10^(5)` Pa and the temperature to `27^(@)` C. The mass of nitrogen that has leaked out is about-
A. 128g
B. 84g
C. 154g
D. 226g
