Question

calculate the number of moles of electron in SO4^ - 2​

Answer 1

So4^-2 contains 6.023×10^23 molecules

Sulfur contains 16 electrons and oxygen contains 8 electrons since 4 oxygens total no of oxygen electrons is 8×4=32

and 2 extra electrons.

(because (-) in chemistry means gain)

So total no Of electrons of is 16+32+2=50

So, total no of electrons in So4^-2 is

50 × 6.023 × 10^23 electrons
