What is the required amount of 65% calcium hypochlorite to achieve the same disinfection effect as 16.68 lbs of chlorine gas?

To determine the required amount of 65% calcium hypochlorite needed to achieve the same disinfection effect as 16.68 pounds of chlorine gas, it's essential to understand the available chlorine content in both chemicals.

Chlorine gas (Cl2) is a known disinfectant, and its effectiveness is measured based on the weight of the actual chlorine. In this case, 16.68 pounds of chlorine gas provides that same weight of elemental chlorine for disinfection.

Calcium hypochlorite (Ca(OCl)2) is a solid chlorine source, and its effectiveness is also measured based on the weight of active chlorine it contains. A 65% calcium hypochlorite solution means that 65% of the weight contributes to the available chlorine.

To calculate how much calcium hypochlorite is needed, you can set up the equation based on the available chlorine content:

1. First, identify how much active chlorine is available in 16.68 lbs of chlorine gas. The molecular weight of Cl2 is 70.9 grams, and for practical calculations relating to disinfection, the equivalent weight of chlorine gas can be considered directly as it relates to weight in pounds for disinfection.

2. Then, calculate the weight
