0.727 g of an unknown metal is reacted with excess concentrated hydrochloric acid according to the reaction below. 0.335 L of hydrogen gas was collected over water on a day when the temperature was 25.0 oC and the pressure was 0.98 atm. The vapor pressure of water at 25.0 oC is 23.8 torr. Report the partial pressure of hydrogen gas in atmospheres, the molar mass of the metal and the atomic symbol for the metal. The ideal gas law constant R = 0.0821 L*atm*K-1mol-1.
