What is the weight percentage range of Anhydrous Ammonia?

Anhydrous ammonia is a form of ammonia (NH3) that has no water content, hence the term "anhydrous," meaning "without water." The weight percentage of anhydrous ammonia is typically very high because it is intended to be a concentrated solution. The correct range of 99.8% to 99.999% reflects that anhydrous ammonia is essentially pure ammonia, which is used in various industrial refrigeration applications, agricultural fertilizers, and chemical processes.

This high concentration of anhydrous ammonia is crucial for its effectiveness in these applications, as it ensures maximum efficiency in refrigeration and other uses. The presence of impurities or water can significantly alter its performance and usability in these contexts, thus emphasizing the importance of maintaining high purity levels.

In contrast, the other choices present ranges that are significantly lower than what is expected for anhydrous ammonia, indicating they do not accurately reflect its concentrated nature.
