To determine the number of moles and the number of atoms in 52 atomic mass units (amu) of helium (He), we need to use Avogadro's number, which relates the number of atoms to the number of moles.
Avogadro's number (NA) is approximately 6.022 × 1023 atoms/mol.
To calculate the number of moles, we can use the formula:
Number of
