sodium chloride is decomposed into the elements sodium and chlorine by means of electrical energy. how many grams of chlorine gas can be obtained from 2.50 mol NaCL

Sagot :

Transitionstateid

Answer:

              88.63 g of Cl₂

Solution:

The Balance Chemical Equation is as follow,

                                     2 NaCl       →      2 Na + Cl₂

Calculating grams of Chlorine Gas;

According to equation,

                  2.0 moles of NaCl produces  =  70.906 g of Cl₂ gas

So,

                     2.50 mole of NaCl will produce  =  X g of Cl₂

Solving for X,

                      X  =  (2.50 mol × 70.906 g) ÷ 2.0 mol

                      X  =  88.63 g of Cl₂
