In simple words, 1 mole is equal to the molecular weight of the substance.Molarity refers to the number of moles of the solute present in 1 liter of solution.The density of 56.6% (w/w) Ammonium hydroxide is 0.9 g/ml at 25☌ which means that the weight of the 1 ml of Ammonium hydroxide is 0.9 g at 25☌.A 56.6% (w/w) Ammonium hydroxide means that the 100 g of Ammonium hydroxide solution contains 56.6 g of NH 4OH.A 28% aqueous solution of ammonia (NH 3) is equal to approximately 56.6% Ammonium hydroxide (Ref: Sigmaaldrich). When ammonia dissolves in water, it forms Ammonium hydroxide.A 56.6% (w/w) concentrated ammonium hydroxide can be obtained from different suppliers. Ammonium hydroxide (NH 4OH) is a clear colorless liquid.
