From a container having 64 g Oxygen, `11.2L` Oxygen gas at STP and `6.022xx10^(23)` Oxygen atoms are removed. Find the mass of the oxygen gas left :

A

zero

B

32 g

C

16 g

D

none

Text Solution

Verified by Experts

The correct Answer is:
B
From a container having 64 g Oxygen ………….
Removed mass `= (11.2)/(22.4)xx32+(6.02xx10^(23))/(6.02xx10^(23))xx16=32g`
mass left `= 64-32 = 32g`.
