chemistry/ partial pressure
posted by Bianca .
N2 was collected over water at 25 degrees C. The resulting pressure was 705 torr. The vapor pressure of water at 25 degrees C is 23.8 mm. What is the partial pressure of N2?

Dalton's LawThe total pressure is the sum of the partial pressures of each gas.
Ptotal = PN2 + PH2O
