A sample of oxygen gas is collected by displacing water from an inverted bottle as shown in the diagram below. The volume of O2(g) collected is 400.0ml at 25 degree Celsius. The atmospheric pressure is 680 torr and the vapor pressure of water at 25 degree Celsius is 23.8 torr. What mass of O2(g) is collected? Cand calculate the mass of KCLO3(s) required to produce the amount of O2(g) given above. 2KCLO3(s)-->2KCL(s)+3O2(g)
