A piece of metal weighing 0.713 g was placed in an eudiometer containing aqueous HCI. After the metal fully dissolved ,23.5 mL of hydrogen gas was collected by displacement of water and a 400 mm column of water was observed. The water temperature was 25 degrees Celcius and the barometric pressure was 758.8 mm Hg ( torr). Refer to the introduction and data sheet to solve the following problems. Calculate the pressure of the hydrogen gas above the water in the column. Calculate the volume occupied by the hydrogen gas at STP. How many equivalent weights (#ew) of the metal were consumed in the reaction? What is the equivalent weight of the metal
