How to make 0.3% ammonia water from 28-30% ammonia hydroxide Can someone tell me how to make 0.3% ammonia water from 28-30% Ammonia hydroxide?
I am trying to make a gallon or 3.78 Liters.
Hint : Ammonia water is actually diluted Ammonium Hydroxide ruled by the following equilibrium :

$$\ce{NH3 + H2O &lt;=&gt; NH4+ + HO-}$$
