For the oxidation-reduction reaction equation given here,
2Rb+Br2 --> 2RbBr
Indicate how many electrons are transferred in the formation of one formula unit of product.
Rb ==> Rb^+ + e
1 mol RbBr contains 1 mol Rb metal which undergoes 1 e per atom change; therefore, 1 mole of electrons is changed for 1 mol RbBr. 1 mol electrons = 6.022E23 individual electrons.
