Use the problem below to answer the question:

When a current is passed through a solution of salt water, sodium chloride decomposes according to the following reaction:

2NaCl + 2H2O → 2NaOH + Cl2 + H2

How many grams of chlorine gas, Cl2, are given off if 7.5 grams of sodium chloride, NaCl, are decomposed?

The molecular mass of NaCl is 58.44 g/mole. The molecular mass of Cl2 is 70.90 g/mole. Using these values, finish the above problem.

_______ grams of chlorine gas

@apoorvk sorry to bother you but can you help me with solving this equation

chmvijay · Answer

2*58.44 gram of NaCl gives =70.9 gram of chlorine
7.5 gram gives=(70.9*7.5) /2*58.44 =4.54 gram of chlorine
