Final answer:
To determine the molar mass of an unknown metal, measure the mass of the sample and convert it to moles using the molar mass. By comparing the calculated molar mass to the known molar mass of metals from the periodic table, you can identify the metal.
Step-by-step explanation:
The molar mass of an unknown metal can be determined by performing a chemical analysis. This involves measuring the mass of the metal sample and converting it to moles using the molar mass of the metal. The molar mass is calculated by dividing the mass of the sample by the number of moles. By determining the molar mass, you can identify the metal based on its known molar mass from the periodic table.
