The answer to your question is 2.14 moles of Cl₂

Explanation:

Data

mass of NaCl = 250 g

moles of Cl₂ = ?

Process

1.- Write the balanced chemical reaction

            2NaCl  +  2H₂O  ⇒  2NaOH  +  Cl₂  +  H₂

2.- Calculate the molar mass of NaCl

 NaCl = 23 + 35.45 = 58.45 g

3.- Convert the mass of NaCl to moles

                         58.45 g of NaCl 1 mol

                        250  g of NaCl x

                          x = (250 x 1) / 58.45

                          x = 4.28 moles

4.- Calculate the moles of Cl₂

                    2 moles of NaCl 1 mol of Cl₂

                   4.28 moles of NaCl x

                   x = (4.28 x 1) / 2

                   x = 2.14 moles of Cl₂

they it depends on if one believes about radioactivity, they make a geiger counter beep but maybe it was going to beep anyway electronics do wierd things all the time or it was programmed to beep near certain metals.
