Respuesta :
So mass = mr * moles
Table salt -> NaCl, Mr = 23+35.5 = 58.5
4/58.5 = number of moles
Multiply the number of moles by 2 and then by 23 to find grams of Na
Multiply number of moles by 35.5*2 for the moles of chlorine gas.

Answer: The mass of [tex]2Na+Cl_2[/tex] required would be, 4 grams.
Explanation:
Law of conservation of mass : It states that the mass can neither be created nor be destroyed but it can only be transformed from one form to another form.
This also means that total mass on the reactant side must be equal to the total mass on the product side.
The chemical equation for the reaction will be,
[tex]2Na+Cl_2\rightarrow 2NaCl[/tex]
According to the law of conservation of mass,
Mass of reactant = Mass of product
Mass of [tex]2Na+Cl_2[/tex] = Mass of [tex]2NaCl[/tex]
Mass of [tex]2Na+Cl_2[/tex] = 4 grams
Hence, the mass of [tex]2Na+Cl_2[/tex] required would be, 4 grams.
