Firstly we will calculate the number of moles in 48g of Mg
No of moles = 48/24 = 2
We have 2 moles of Mg^+2.
Now we will calculate the number of Mg+2 ions present in 48 g .
No of atoms = 2N°
Now we will calculate no electrons in Mg+2
2 electrons are already removed
So total no of electrons will be multiplied by 10.
2N° x 10
= 20N°
( Please note that N° is Avogadro's number )
