Calcium hypochlorite contains what percent of available chlorine by weight?

The correct answer is: 25%

Calcium hypochlorite contains 25% of available chlorine by weight, which means that for every 100 grams of calcium hypochlorite, 25 grams of chlorine is available. This option is correct because it is the only one that states a percentage below 100 and higher percentages would result in a greater amount of available chlorine. Option B (45%) is incorrect because it is a higher percentage than 25%, so it would result in a greater amount of available chlorine, making it higher than the actual value. Option C (65%) and D (85%) are also incorrect because they are even higher percentages, which would result in even greater amounts of available chlorine and are therefore not accurate representations of the amount of chlorine in calcium hypochlorite.
