The oxygen gas emitted from an aquatic plant during photosynthesis is collected over water at a temperature of 25 degrees celsius and a total pressure of 762 torr. What is the partial pressure of the oxygen gas?

What formula do I need to use?

Total pressure= sum of the partial pressures

762 torr-water vapor pressure=O2 pressure

water vapor pressure at 25慢 =23.756 torr

But check the reference value.
