8 Is my best guess. Hope this helps
The standard temperature and the pressure for a gas are 273 K and 1 atm (1.0 x 10⁵ Pa) respectively.
For this question, combined gas law can be added.
PV/T = K (constant)
for both situations that law can be added as;
P₁V₁/T₁ = P₂V₂/T₂
P₁ = 97 kPa P₂= 1.0 x 10⁵ Pa
T₁ = 303 K T₂ = 273 K
V₁ 140 mL V₂ = ?
V₂ = 122.3 mL
Hence, the volume of gas at STP = 122.3 mL

Sharing of electrons always means its a covalent bond, and unequal means it is polar, so it is a polar covalent bond
