Final answer:
To convert moles of manganese to atoms, multiply the number of moles by Avogadro's number (6.022×1023 atoms/mol).
Step-by-step explanation:
To convert moles of manganese to atoms of manganese, you would multiply the number of moles by Avogadro's number, which is 6.022×1023 atoms/mol. This is because one mole of any substance contains Avogadro's number of atoms, molecules, or formula units. For example, if you have 2 moles of manganese, you would multiply 2 by 6.022×1023 to get the number of atoms.
This can be expressed as the following equation: Number of atoms = moles × Avogadro's number. This is fundamental in stoichiometry for converting between the macroscopic scale of substances measured in moles and the microscopic scale of individual atoms.
