Nitrogen(75.5 kPa), oxygen (19.2 kPa), carbon dioxide(0.05 kPa) and water vapor(4.3 kPa) are the usual atmospheric components. What is the total atmospheric pressure in kPa?

  • chem -

    See Dalton's Law of partial pressure. That law says that the total pressure is the sum of the partial pressures of each gas.
