Asample of oxygen gas is collected over water at 22°c and 98.67 kpa pressure. if the partial pressure of the water is 2.67 kpa, the partial pressure of the oxygen is?

The partial pressure of the oxygen gas is 96.00 KPa

Explanation:

The law of partial pressures states that, in a mixture of gases, the total pressure of the mixture is equal to the sum of the individual pressures of each gas, as if each gas were alone in the mixture.

So:

Total pressure = ∑ individual pressuresTotal pressure = Partial pressure of the water + Partial pressure of oxygen98.67 KPa = 2.67 KPa + Partial pressure of oxygenPartial pressure of oxygen = 98.67 KPa - 2.67 KPaPartial pressure of oxygen = 96.00 KPa ← answer

Olá. porque a reação na temperatura é muito rapida a do copo : )
