Location. Rhodia Drive. Nov 11, 2008. #2. Yes I know it. Works well for a lot of things, too well. If your gold isn't already pure, any PGMs will come down with the Hydrazine Hydrates,Hydrazine has a molecular weight of 32 and the monohydrate has a molecular weight of 50. The ratio of their weight is 32/50 or 0.64. Therefore, 100% monohydrate would contain 32/50 or 64% hydrazine.
