Question

How many oxygen atoms are in 10 formula units of AI2(SO4)3

Answer 1

there are 120! because:

04 multiplied by 3 to make 12,

and since there are 10 units,

you multiply 12 by 10,

you get 120 oxygen atoms!

Answer 2

• 120 Oxygen atoms

Data given

• Formula unit of AL2(SO4)3 =10
• 1 formula unit of AL2(SO4)3 contain oxygen atoms = 12
• 10 formula unit of AL2(SO4)3 contain oxygen atoms = 12 × 10
• 1 formula unit of AL2(SO4)3 contain oxygen atoms = 120
