Assume that the partial pressure of sulfur dioxide, PSO2 , is equal to the partial pressure of dihydrogen sulfide, PH2S , and therefore PSO2=PH2S. If the vapor pressure of water is 27 torr, calculate the equilibrium partial pressure of SO2 (PSO2) in the system at 298 K. Express the pressure in atmospheres to two significant figures. PSO2= __ atm
