Suppose dry air near sea level has the following composition by volume: N2, 78.08 percent; O2, 20.94 percent ; Ar, .93 percent; CO2, .05 percent. If the atmospheric pressure is 1.00 atm, calculate the partial pressure of each gas in atm. PN2 PO2 PAr PCO2 Calculate the concentration of each gas in moles per liter at 0 degrees C cN2 cO2 cAr cCO2 (enter answer in scientific notation for this one)
