How many electrons are present in
2 x 10-3 moles of so-2 ion
​

Answer 1

598.08 × 10^20

total number of electron = 2× 10^-3

we know,

1 mole = 6.23× 10^23 atom

total number of atoms = 2×10^-3 × 6.23×10^23 = 12.46 × 10^20

number electron in one so2 ion = 16+8+8= 48

total number of electron in 2× 10^-3 = 12.46 × 10^20 × 48

= 598.08 × 10 ^ 20
