A sample of 310.2 mL of wet nitrogen gas was collected over water at a total pressure of 723 torr and a temperature of 21.0 C. (The vapor pressure of water at 21.0C is 18.7 torr.) The nitrogen was produced by the reaction of sulfamic acid, HNH,SO3, with 388.8 mL of a solution of sodium nitrite according to the following equation NaNO2 + HNH2SO4+ N2 + NaHSO4 + H2O Calculate what must have been the molar concentration of the sodium nitrite M e Textbook and Media Hint Assistance Used Reduce the total pressure by the vapor pressure of water to get the "dry" gas pressure
