Question

What is the total pressure (in mmHG) in a container filled with carbon dioxide at 4 kpa, water vapor at 7 kna and oxygen gas at Okna?

Answer 1

To solve this problem, we need to convert the given pressures of each gas into a common unit, such as mmHg, and then add them together to get the total pressure.

1 kPa is equivalent to 7.5 mmHg, so we can convert the pressures as follows:

Carbon dioxide: 4 kPa x 7.5 mmHg/kPa = 30 mmHg

Water vapor: 7 kPa x 7.5 mmHg/kPa = 52.5 mmHg

Oxygen: 0 kPa x 7.5 mmHg/kPa = 0 mmHg

The total pressure is the sum of these partial pressures:

30 mmHg + 52.5 mmHg + 0 mmHg = 82.5 mmHg

Therefore, the total pressure in the container is 82.5 mmHg.
