WebThe relative formula mass of copper(II) sulfate crystals, CuSO 4.5H 2 O: M r of CuSO 4.5H 2 O = 63.5 + 32 + (4 x 16) + 5 x [(2 x 1) + 16] = 249.5. Be careful with things which contain water of crystallisation like the copper(II) sulfate crystals in this example. WebAmmonium iron(II) sulfate, or Mohr's salt, is the inorganic compound with the formula (NH 4) 2 Fe(SO 4) 2 (H 2 O) 6.Containing two different cations, Fe 2+ and NH + 4, it is classified as a double salt of ferrous sulfate and ammonium sulfate.It is a common laboratory reagent because it is readily crystallized, and crystals resist oxidation by air. WebThis problem has been solved! You'll get a detailed solution from a subject matter expert that helps you learn core concepts. Question: Calculate the formula mass of ammonium sulfate, (NH4)2SO4. Keep at least one decimal place in atomic masses from the periodic table. shoes in dreams biblical meaning
