![]() ![]() Thus it is a very similar compound to both ferrous sulfate and ferric sulfate. The density of iron II ammonium sulfate hexahydrate is approximately 271 g/cm3 which is slightly higher than both ferrous sulfate (FeSO 4) and ferric sulfate (Fe 2(SO 4) 3). ![]() The solubility decreases as the temperature increases, with a solubility of 1.5 gm/100ml at 60 degrees C and 2.8 gm/100 ml at 120 degrees C. It has a solubility in water of 0.2g/100 ml at 20 degrees C. The solubility of iron ii ammonium sulfate hexahydrate is very high. On heating the compound above its melting point it first melts, then decomposes into a liquid, and finally solidifies again before finally cooling below its melting point. Phase diagram showing how iron ii ammonium sulfate hexahydrate changes between different phases at different temperatures. Thus the molar mass of a molecule is given as: molecular weight = molecular formula * density * molality / 8.0 This explains the molar mass of iron ii ammonium sulfate hexahydrate. The molar mass of an ion is the mass of an ion in grams. All three compounds have the same enthalpy per mole at 298K, with their values being 1.981 J/mol, 1.906 J/mol and 1.992 J/mol respectively. All three compounds have the same enthalpy per mole at 0K. The molar mass of this compound is very similar to that of ammonia and iron (III) sulfate with the difference between all three compounds being 2,273 g/mol. The molecular weight of iron ii ammonium sulfate hexahydrate is 707.34 kg/mol which is equivalent to a molecular weight of 273.681 g/mol. It also matches the properties of iron (III) sulfate and very closely that of ferrous sulfate(FeSO 4). This value is very close to both ammonia and ammonium hydroxide. The density of iron ii ammonium sulfate hexahydrate is 2181 kg/m 3 which gives it a molar mass density of 1 gm/cm 3 . The melting point of iron ii ammonium sulfate hexahydrate is 350 degrees Celsius with a decomposition temperature of 428 degrees Celsius. This is the temperature at which the compound decomposes. This is a very similar boiling point to normal ammonia. The boiling point of iron ii ammonium sulfate hexahydrate is 428.5 degrees Celsius with the melting and boiling temperatures only 7.5 degrees Celsius apart.
