Ptotal = pCO2 + pH2O
Ptotal is what you want.
You know pCO2 is 740.
Look in your text/notes and find the vapor pressure of H2O at 25 c. That is the pH2O. Calculate Ptotal.
A student collects gas over water after reacting sodium bicarbonate with hydrochloric acid. The watwr in the collector is the same both inside and out. The partial pressure of the carbon dioxide gas collected is 740 atm.if the temperature at the time of the experiment is 25c what was the barometric pressure at the time of the experiment?
