Answer:
Based on the information provided, it seems that the purpose of the experiment is to determine the molar mass of a metal and the molar mass of hydrogen using different methods. The three options listed all involve different approaches to determining the molar mass of the metal and/or hydrogen.
Option 1 involves finding the molar mass of the metal by measuring the moles of hydrogen produced when the metal is oxidized. This method is based on the principle of the Law of Conservation of Mass, which states that the mass of the reactants must be equal to the mass of the products in a chemical reaction. By measuring the amount of hydrogen produced, the amount of metal consumed can be calculated, and from there the molar mass of the metal can be determined.
Option 2 involves finding the molar mass of hydrogen by measuring the moles of metal lost when the metal is reduced. This method is based on the same principle as Option 1, but instead focuses on the reduction of the metal and the resulting loss of metal mass. By measuring the amount of metal lost, the amount of hydrogen produced can be calculated, and from there the molar mass of hydrogen can be determined.
Option 3 involves finding the molar mass of hydrogen by measuring the moles of metal gained when the metal is oxidized. This method is similar to Option 1, but instead of measuring the moles of hydrogen produced, it focuses on the amount of metal gained during oxidation. By measuring the amount of metal gained, the amount of hydrogen consumed can be calculated, and from there the molar mass of hydrogen can be determined.
Overall, the purpose of the experiment is to determine the molar masses of a metal and hydrogen using different methods based on the principles of stoichiometry and the Law of Conservation of Mass.
