A 1 L flask contains 32 g `O_(2)` gas at `27^(@)C`. What mass of `O_(2)` must be released to reduce the pressure in the flask to 12.315 atm?

A

8 g

B

16 g

C

24 g

D

0 g

Text Solution

Verified by Experts

The correct Answer is:
B
`pV=nRT=w/mRT`
`:.w=(pVm)/(RT)=(12.315xx1xx32)/(0.0821xx300)=16g`
`:. 0_(2)` to be released = 32 -16=16 g
