Question

How many grams of chlorine gas are needed to make 117 grams of sodium chloride

Answer 1

Answer: 70.9709 g

Step-by-step explanation:

According to the chemical equation, 2 mol of Na react with 1 mol of chlorine molecule to produce 2 mol of NaCl.

Mol = 117 g/2(58.44) gmol^-1

Mol =1.001

Therefore, →g of Cl = 1.001(70.90)

.˙ . 70.9709 g
