oxygen gas is generated by the thermal decomposition of potassium perchlorate. the oxygen gas is captured by water displacement at a water temperature of 20 degrees C resulting in a water vapor pressure of 0.0231 atm. if the pressure inside of the eudiometer is equalized to barometric pressure (0.987 atm), what is the pressure of the oxygen gas in the eudiometer?
