Answer:

= 664.10 mmHg

Explanation:

According to pressure law the pressure of a fixed mass of a gas is directly proportional to the absolute temperature.

Therefore;

P1/T1 = P2/V2

Standard temperature is equal to 0°C, which is 273.15 K.

In this case;

P1/T1= P2/T2

P1 = 778 mmHg

T1 = 47.0 + 273 K

    = 320 K

P2 = ?

T2 = 0° C = 273.15 K

P2 =P1T2/T1

    = (778 × 273.15)/320 K

    <u>= 664.10 mmHg</u>
