How many fe(ii) ions are there in 15.0 g of feso4?

Answer : The number of Fe(II) ions present are

Explanation : Given,

Mass of = 15.0 g

Molar mass of   = 152 g/mole

First we have to calculate the moles of

Now we have to calculate the number of Fe(II) ions.

In , there 1 atom of iron ion and 1 atom of sulfate ion.

As we know that,

1 mole of substance always contains number of atoms or ions.

As, 1 mole of contains number of Fe(II) ions.

So, 0.0987 mole of contains number of Fe(II) ions.

Therefore, the number of Fe(II) ions present are
