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

increased stability in the completion of fluorine's outer shell.
