Question

what is the mass (in grams) of chlorine required to react with 10.0 g of sodium metal to produce sodium chloride?

Answer 1

The mass of chlorine required to react with 10.0 g of sodium metal to produce sodium chloride is 15.26 g.

The balanced chemical reaction is :

           2Na + Cl₂ → 2NaCl

Given data :

Mass of sodium = 10.0 g

Number of moles of Na -

Number of moles =  Given mass  

                                    Molar mass

Number of moles = 10.0 g = 0.43 mol

                                  23 g

Comparing moles of Na and Cl₂ from the balanced chemical equation,

                                            Na        :        Cl₂

                                             2          :         1

                                             0.43     :         1 x 0.43 = 0.215 mol

                                                                   2

Mass of chlorine gas :

          (molar mass of chlorine = 71 g)

Mass of chlorine = number of moles x molar mass

Mass = 0.215 mol x 71 g/mol

          = 15.26 g
