Each calcium hypochlorite tablet weighs 0.42 lb. In a disinfection calculation, what is the weight of one tablet?

• A. 0.25 lb
• B. 0.42 lb
• C. 0.5 lb
• D. 0.75 lb

Answer: (B)

The weight of one tablet is simply the amount given for a single item. Since each calcium hypochlorite tablet weighs 0.42 lb, one tablet weighs 0.42 lb. In disinfection calculations you multiply this weight by the number of tablets to get the total weight used. The other numbers don’t fit because they don’t match the stated weight per tablet.
