Concentrated ammonium hydroxide (aq ammonia) has a density of 0.90g/mL and is 28% by mass ammonia. Determine the molar concentration of ammonium hydroxide.

  • chemistry -

    If it is 28 percent ammonia, then it contains .90*.28 grams ammonia/ml.

    or in a liter, 900*.28 grams/liter

    divide that by the mole mass of NH2, and you have molarity.
