Question

explain how there are 2 moles of electrons in 24 gram of magnesium 2 positive ion​

Answer 1

1 molar mass is answer of magnesium

Answer 2

GAM of Mg² ≈ 24g

No. of moles of Mg² in 24g = 1 mol

therefore :-

No. of electrons in 24g of Mg = no. of electrons in 1 mol of Mg² ion .

Mg has 12 electrons in its neutral state therefore Mg+2 ion will have 10 electrons in its ionic state .

therefore , one mole of Mg+2 will have 10×1 moles of electrons .

no. of electrons in the given situation is equal to 60.22×10²³ .

hence, the no. of electrons present is not equal to 2 moles rather it is 60.22×10²³ .

Although , 1 mol of Mg+2 ion has 2 moles of +2 charge but it still has 60.22×10²³ electrons .

Therefore :-

No. of electrons in 24g of Mg+2 is =

60.22×10²³

No. of charge in 24g of Mg+2 is =

2 moles .

hope that helps .
