Question

A gas sample of Xe occupies 10-liter balloon at 27 degrees C under a pressure of 1.2 atm. Approximately what volume would the gas occupy at 350 K and 2 atm of pressure? A. 7 liters B. 9 liters C. 13 liters D. 18 liters

Answer 1

A. 7 liters
I'm quite sure that's what it is

Answer 2

Answer:

Option A, 7 L

Explanation:

Ideal gas equation,

$\frac{P_1 V_1}{T_1} = \frac{P_2 V_2}{T_2}$

P1 = 1.2 atm

V1 = 10 L

T1 = 27 °C = 27 + 273 = 300 K

P2 = 2 atm

T2 = 350 K

$\frac{P_1 V_1}{T_1} = \frac{P_2 V_2}{T_2}$

$\frac{1.2\times 10}{300} = \frac{2\times V_2}{350}$

$V_2=\frac{1.2\times 10\times 350}{2\times 300} = 7\ L$

So, option A is correct
