Answer:

Explanation:

We shall apply gas law equation

[tex]\frac{P_1V_1}{T_1} =\frac{P_2V_2}{T_2}[/tex]

P₁ = 221 X 10³

V₁ = 255 L

T₁ = 273 + 125

= 398 K

P₂ = 1.01 x 10⁵ ( Standard pressure )

V₂ = ?

T₂= 273 K ( standard temperature is 0 degree )

Putting the values above in the gas equation

[tex]\frac{221000\times 255}{398} =\frac{101000V_2}{273}[/tex]

V₂ = 382.73 L .
