QNEET-2022-Ch-480: NEET 2022 Chemistry - Class 11 NEET-2022-Ch-480 Solution: A vessel contains 3.2 g of dioxygen gas at STP (273.15 K and 1…
A vessel contains 3.2 g of dioxygen gas at STP (273.15 K and 1 atm pressure). The gas is now transferred to another vessel at constant temperature where pressure becomes one third of the original pressure. The volume of new vessel in L is: (Given: molar volume at STP is 22.4 L) 67.2 6.72 2.24 22.4
Multiple Choice Options
- A 67.2
- B 6.72
- C 2.24
- D 22.4
Step-by-Step Verified Solution
At constant temperature and amount
P 1 V 1 = P 2 V 2
P 1 V 1 = P 1 3 V 2 [ _ P 2 = P 1 3 ]
V 2 = 3 V 1
mole of O 2 ( g ) = 3.2 32 = 0.1 mole
Volume of O 2 ( g ) = ( 0.1 _ 22.4 ) L = 2.24 L
At STP (V 1 )
V 2 = 3 V 1 = 3 _ 2.24
= 6.72 L
