I don’t know how to explain it, but when there are 8 outermost outer nuclear electrons, it’s the most stable time, lose e- will make it unstable

Answer:
n= 0.303mol
Explanation:
From PV= nRT
R= PV/nT
Comparing 2-systems of baloons
P1V1/n1T1 = P2V2/n2T2
Since pressure and temperature are constant
V1/n1= V2/n2
23.5/5.2 = 14.9/n2
Simplify
n2= 0.303mol
