A gas tank holds 285 L of propane, C3H8, at 530. mm Hg. What is the volume of the propane at standard pressure? A)408.7L B)408.7 mm Hg C)198.8 mm D)198,8

Respuesta :

Answer:

option D

Explanation:

Given,

V₁ = 285 L

P₁ = 530 mm Hg

Standard pressure

P₂ = 760 mm Hg

V₂ = ?

Using relation between pressure and volume

[tex]\dfrac{P_1}{V_2}=\dfrac{P_2}{V_1}[/tex]

[tex]\dfrac{530}{V_2}=\dfrac{760}{285}[/tex]

[tex]V_2 = 198.75\ L[/tex]

Hence, volume of the propane at standard pressure is equal to 198.8 L.

Hence, the correct answer is option D.
