Answer:

option B.

Step-by-step explanation:

Given,

Volume,V₁ = 22.8 L

T₁ = 313 K

P₁ = 4 atm

T₂ = 341 K

P₂ = ?

Volume is constant.

Using ideal gas law


(P_1)/(T_1)=(P_2)/(T_2)


(4)/(313)=(P_2)/(341)


P_2 = (4)/(313)* 341


P_ 2 = 4.36\ atm

Pressure of the tank is equal to 4.36 atm.

Hence, the correct answer is option B.
