Question

Nitrogen molecules has radius of about 0.2 nm. Assuming that nitrogen molecule is special in shape , calculate the volume of a single molecule of N2 and the percentage of empty space in one mole of N2 gas at STP.​

Answer 1

⚡⚡Here is your answer⚡⚡

The pressure on the wall is exerted by normal component of force.

p= F/A = 1/A ◇p/◇t = 1/A [mv cos thita -(-mv cos thita)/1/N]

where N =number of collisions per second

:- P= 2Nmv coz thita/A

= 2×10^23×3.32^-27×10^5 cos45°/2×10-4

= 2.35 × 10^5 Pa

Answer 2

Explanation:

The pressure on the wall is exerted by normal component of force

P=F/A=1/A=p/t=1/A

N= Number of collins per second

P= 2Nmv Cozthita/A

=2.35×10^5pa
