Problem- A volume of 203 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. Calculate the atomic mass of the metal. A 0.194 gram sample of a metal, M, reacts completely with sulfuric acid according to: M + H2SO4 --> MSO4 + H2
