Asked by Austin
Oxygen gas, from the decomposition of KClO3, was collected by water displacement. The pressure and temperature in the lab during the experiment were 451.0 torr and 20.0 C. What was the partial pressure of oxygen?

Look up the vapor pressure of H2O at 20 C. This is pH2O.
Then Ptotal = pO2 + pH2O
You know Ptotal and pH2O, solve for pO2.
Then Ptotal = pO2 + pH2O
You know Ptotal and pH2O, solve for pO2.
