A 0.279 g sample of a metal, M, reacts completely with sulfuric acid according to M(s) + H₂SO4 (aq) → MSO4 (aq) + H₂(g) A volume of 291 mL of hydrogen is collected over water; the water level in the collecting vessel is the same as the outside level. Atmospheric pressure is 756.0 Torr, and the temperature is 25 °C. The vapor pressure of water at 25 °C is 23.8 Torr. Calculate the molar mass of the metal.
