Ammonium Hydroxide

I have seen ammonia solutions advertised as ammonium hydroxide and I was wondering if an ammonia solution of a given percentage was the same as the same percentage ammonium hydroxide solution.

Ex: 10% ammonia solution contains 10g of ammonia per 100g of solution. Would 100g of "ammonium hydroxide" contain 10g of ammonia (molar mass 17g/mol)? Or ammonium hydroxide (35g/mol)?

It generally means what it says. 10% NH3 means 10% NH3, 10% NH4OH means 10% NH4OH. 28% Ammonia (NH3) is equal to approximately 56.6% Ammonium Hydroxide.

Ok, thanks for clearing that up.
