A student used 1.6 moles of NaCl. How many miles of Chlorine gas gas were produced? Use this equation: 2NaCl + 2H2O = 2NaOH + Cl2 + H2

The answer to your question is 0.8 moles of Cl₂

Explanation:

Data

moles of NaCl = 1.6

moles of Cl₂ = ?

Process

1.- Check if the reaction is balanced

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

This reaction is balanced.

2.- Use proportions and cross multiplication to solve this problem. Consider the coefficients of the balanced reaction.

                 2 moles of NaCl 1 moles of Cl₂

                 1.6 moles of NaCl  x

                                             x = (1.6 x 1) / 2

                                             x = 1.6 / 2

                                             x = 0.8 moles of Cl₂
