If you have 0.08157 moles of al(clo4)3… a) how many moles of al3+ ions do you have? b) how many moles of clo4 – ions do you have? c) how many moles of oxygen atoms do you have?

Aluminum chlorate ionizes as follows,

1 mol Aluminum chlorate ionizes to give 1 mole Aluminum ion and 3 moles of chlorate ion. Each mole aluminum ion has 4 * 3 = 12 moles of Oxygen atom.

Moles of = 0.08157 mol

a) Moles of =

b)Moles of

c) Moles of O atom =

the answer is barium and copper bromide
