When excess water is added to a mixture of citric acid and sodium bicarbonate present in a bath bomb, the following reaction takes place C6H3O7(s) + 3 NaHCO3(s) + HO(l) Na3C6H5O(aq) + 4HO(l) + 3 CO(g) Calculate the volume of CO gas collected over water at 38.0 C when a mixture of 43.5 g of citric acid and excess sodium bicarbonate is added to a tub of water if the total pressure is 725 torr. The vapor pressure of water at 38.0 C is 49.7 torr
