A 0.487 g sample of a metal, M, reacts completely with sulfuric acid according to the reaction M(s) + HSO4(aq) ->> MSO4 (aq) + H(g) A volume of 225 mL of hydrogen gas is collected over water; the water level in the collecting vessel is the same as the outside level. Atmospheric pressure is 1.0079 bar and the temperature is 25 C. The vapor pressure of water at 25 C is 0.03167 bar. Calculate the molar mass of the metal. molar mass: 6.379 g/mol
