Question

What is the number of moles and number of atoms 52 amu of He?

Answer 1

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 (N_A) is approximately 6.022 × 10²³ atoms/mol.

To calculate the number of moles, we can use the formula:

Number of
