To determine how many atoms are in 2 moles of calcium, we can use Avogadro’s number, which is approximately 6.022 × 1023 particles (atoms, molecules, etc.) per mole.
So, if we have 2 moles of calcium, we can calculate the number of atoms as follows:
Number of atoms = number of moles × Avogadro’s number
Number of atoms = 2 moles × 6.022 × 1023 atoms/mole
This gives us:
Number of atoms ≈ 1.2044 × 1024 atoms
Therefore, there are approximately 1.2044 × 1024 atoms in 2 moles of calcium.
