Answer:

= 498.13 mmHg

Explanation:

Using the combined gas law;

P1V1/T1 =P2V2/T2

in this case; P1 = 725 mmHg, V1 = 375 mL and T1 = 25°C + 273 = 298 K

P2 = ?  V2 = 500 mL and T2 (standard temperature) = 0°C + 273 = 273 K

P2 = P1V1T2/T1V2

     = (725 × 375 × 273)/(298 × 500)

     <u>= 498.13 mmHg </u>
