[QUOTE="symbolipoint, post: 6854808, member: 58864"] The desired finished concentration is 16 mg. of ammonium hydroxide per 1000 ml. of solution. Helpful? Let me jump ahead... The amount of GRAMS of the base you'd have if you took v ml of the base solution(which is 18%) is ((0.18 grams ammnmhydxd)/(1 gram stock))((0.926 grams stock)/(1 ml. stock))v .Some simplifications and keeping in mind you want to prepare solution resulting in 16 mg. per 1000 ml, ((0.18)(0.926)v)/1000=16 [/QUOTE]
