Answer:

P_2 =0.51  atm

Explanation:

Given that:

Volume (V1) = 2.50 L

Temperature (T1) = 298 K

Volume (V2) = 4.50 L

at standard temperature and pressure;

Pressure (P1) = 1 atm

Temperature (T2) = 273 K

Pressure P2 = ??

Using combined gas law:

[tex]\dfrac{P_1V_1}{T_1} = \dfrac{P_2V_2}{T_2} \\ \\ \dfrac{1 *2.5}{298} = \dfrac{P_2*4.5}{273}[/tex]

[tex]0.008389261745 \times 273 = 4.5P_2[/tex]

[tex]P_2 =\dfrac{0.008389261745 \times 273 }{4.5}[/tex]

[tex]P_2 =0.51 \ atm[/tex]
