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?

Answer 1

balance the chemical equation.

NaCl>> Na + 1/2 Cl2

so for 2.5mol NaCl, you get 1.25 mole of Cl2. Change that to grams

Answer 2

88.75gms

Answer 3

1 mol cl2/ 2 mol nacl - Mole Ratio

2.5 mol NaCl* 1 mol Cl2/ 2 mol NaCl
=1.25 mol Cl2

1.25 mol Cl2 * 70.9g Cl2/ 1 mol Cl2
= 88.63 g Cl2

Answer 4

Sodium chloride is decomposed into the elements sodium and chlorine by means of

electrical energy .

NaCl rightwards arrowNa+Cl2

Balance the chemical equation. Then find the mass of chlorine gas, in grams, is obtained from the process?
