Answer:

1429.32 mmHg

Explanation:

Initial Pressure P1 = 3000.0mmHg

Initial Temperature T1 = 500.0°C + 273 = 573 K ( Converting to kelvin temperature)

Final Temperature T2 = 0.00°C + 273 = 273 K ( Converting to kelvin temperature)

Final Pressure P2 = ?

The pressure of a given amount of gas is directly proportional to the absolute temperature provided volume remains constant.

This is given by the mathematical expression;

P1 / T1 = P2 / T2

Inserting the values;

3000 / 573 = P2 / 273

P2 = 273 * 3000 / 573

P2 = 1429.32 mmHg
