What is the erg for anhydrous?

The term "erg" can refer to a unit of energy in the centimeter-gram-second (CGS) system, where 1 erg equals 10^-7 joules. However, if you're referring to "ERGs" in a different context, please clarify. Anhydrous typically means "without water," often used in chemistry to describe substances that lack water of hydration. For example, anhydrous salts are those that do not contain water molecules in their crystal structure.
