Oxygen gas is collected over water. The atmospheric pressure is 748 mmHg, and the temperature of the oxygen is 29 ºC. The pressu

KonstantinChe [14]

The pressure of the oxygen gas collected : 718 mmHg

<h3>Further explanation</h3>

Given

P tot = 748 mmHg

P water vapour = 30 mmHg

Required

P Oxygen

Solution

Dalton's law of partial pressures states that the total pressure of a mixture of gases is equal to the sum of the partial pressures of the component gases

Can be formulated:

P tot = P1 + P2 + P3 ....

The partial pressure is the pressure of each gas in a mixture

P tot = P H₂O + P Oxygen

P Oxygen = 748 mmHg - 30 mmHg

P Oxygen = 718 mmHg
