How many total atoms are in a 1.04 mol sample of Iron (III) Oxide (Fe2O3)?

Question

Question

Answer 1

Answer #1

1 mole of any substnace contains 6.023*10²³ molecules

1 molecules of Fe2O3 contains 2 atoms of Fe and 3 atoms of O

so total atoms in 1 molecules of Fe2O3= 5

1.04 mole of Fe2O3 ontains 6.023*10²³* 5*1.04 atom total =31.32*10²³ atoms ( total)
