The answer is e.

Explanation:

We take:

$T_{1}=253K$

$V_{1}=2.00 l$

$P_{1}=0.14atm$

$V_{2}=4.50 l$

$T_{2}=330K$

Taking the gas as an ideal gas, we can use the ideal gas law:

$\frac{PV}{nRT}$

⇒ $n=\frac{P_{1}V_{1}}{RT_{1}}$ ⇒ n=0.013mol

Then:

$P_{2}=\frac{nRT_{2}}{V_{2}}$ ⇒ $P_{2}=0.0811 atm$

Taking R=0.08205atmL/molK.

A, also known as the repetition of the phrase "when I watch you." Sorry that no one answered your question sooner.
