Determination of the Relative Atomic Mass of Metals

In experiment C1.1.1.1, the molar mass of some base metals will be determined. In order to do so, those metals - magnesium, for example - will be reacted with acids. Different metals of the same weight produce different quantities of hydrogen. When using the same quantity of material, the same quantities of hydrogen are produced. This way, the relative molar mass of the respective metals can be determined.
