Calculate the total number of electrons in 48g of so4

Answer 1

mol weighs [ (4*16 ) + 32 ] grams for 6*10^23 molecules
48 g * 6*10^23 molecules/ 96 grams = 3*10^23 molecules
now electrons per molecule
google lewis structure of SO4 to get electrons per molecule

Answer 2

Remember those are the valence electrons.
