The percent by mass of cobalt ii in coso4
It forms by the reaction of metallic cobalt, its oxide, hydroxide, or carbonate with aqueous sulfuric acid: Co + H2SO4 + 7 H2O → CoSO4(H2O)7 + H2 CoO + H2SO4 + 6 H2O → CoSO4(H2O)7 The heptahydrate is only stable at humidity >70% at room temperature, otherwise it converts to the hexahydrate. The hexahydrate converts to the monohydrate and the anhydrous forms at 100 … Webb12 aug. 2011 · 2 O or CoCl 2 •6H 2 O. As the formula indicates, water forms a definite percentage of the weight of any hydrate. For example, the weight of a mole of CuSO 4 •5H 2 O is 250 grams (this is the molar mass of CuSO 4 •5H 2 O). A mole of CuSO 4 •5H 2 O contains 5 moles of water (which corresponds to 90 grams of water) as part of its …
