How many particles are in 50 g of aluminium?

To calculate the number of particles in 50 g of aluminium, first determine the number of moles using the equation moles = mass / Mr, (1.85 moles of aluminium (50/27 = 1.85 mol)) then multiply the number of moles by Avogadro's constant (1.85 × 6.02 × 10^23 = 1.11 × 10^24 particles).
