Based on my scale, I have 35g of aluminum. How many aluminum atoms is this?

Answer:One mole of a substance contains 6.02*10∧23 particles,

1 mole of a aluminium contains 27 g

35 g of aluminium contains 35/27 = 1.296 moles

Thus, the number of particles will be 1.296 * 6.02 * 10∧23

= 7.804 * 10∧23 particles,

Hence, 35 g of Aluminium contains 7.804 * 10∧23 atoms
