The overall order of a reaction is directly
related to the reaction mechanism of the reaction. The reaction mechanism is
defined by the reaction rate equation. In this case, we are given by the
equation, Rate=k. The order of this reaction is zero since the rate is
not dependent on the concentration of reactants or products.
During a reaction, there are reactants and products. Reactants are the elements that are being added. Products are the result of the reactants.
2Na + Cl2 are the reactants.
2NaCl is the Product.

2.4 mol NaSO2 × (6.02×10^23) f.units ÷ 1 mol
=1.44480000×10^25
Approximately 1.4×10^25, if you use sig.figs.
