What is the weight percentage of water in relation to Anhydrous Ammonia?

Anhydrous ammonia is a compound that consists entirely of ammonia molecules without any water present. In its pure form, anhydrous ammonia contains negligible amounts of water, which can generally be in the range of 0.2% to 0.001%. This is extremely low and indicates that anhydrous ammonia is, as the name suggests, devoid of water.

This small percentage comes into play when considering operational scenarios where moisture might inadvertently be introduced, but in controlled environments, the goal is to maintain ammonia in its anhydrous state, which means as free from water as possible.

The other percentage ranges all suggest significant amounts of water, which would not align with the properties or intended usage of anhydrous ammonia in industrial refrigeration settings, where even small traces of moisture can lead to issues such as corrosion, reduced efficiency, or complications in chemical interactions.
