This most likely refers to CoSO4, or cobalt II sulfate, which contains 3 elements: cobalt, sulfur, and oxygen.
However, capitalization is important in writing chemical formulas, and the lack of capitalization creates some ambiguity.
COSO4, would also contain 3 elements: carbon, sulfur, and oxygen, though this particular configuration is unlikely.

There are two elements, carbon and hydrogen.
This solution should contain 0.500 grams anhydrous cobalt(II)-sulfate (CoSO4) per litre.When using mono- or heptahydrate, increase the weighted mass by the relevant molar mass ratio.Molar masses:154.996 g/mol CoSO4 (anhydrous)173.01 g/mol CoSO4.H2O (monohydrate) ==> ratio 173/155 = 1.12, so 0.556 g/L281.103 g/mol CoSO4.7H2O (heptahydrate) ==> ratio 281/155 = 1.81, so 0.905 g/L
The current periodic table contains 118 elements, as of April 2010, but many more may still be discovered.

The name of the ionic compound CoSO4 is cobalt(II) sulfate.
Cobalt tetraoxosulphate (vi) ion
Cobalt (II) sulfate.
The balanced equation between cobalt oxide (CoO) and sulfuric acid (H2SO4) is: CoO + H2SO4 -> CoSO4 + H2O
Yes, CoSO4 (cobalt(II) sulfate) is a strong electrolyte because it completely dissociates into its ions (Co2+ and SO4 2-) in solution, allowing it to conduct electricity effectively.
CoSO4 is the chemical formula for cobalt(II) sulfate, a compound composed of cobalt, sulfur, and oxygen. It is a blue crystalline solid that is commonly used in the production of pigments, catalysts, and electroplating applications.
The oxidation number of Co in CoSO4 is +2. This is because the oxidation number of oxygen is -2 and the overall charge of the sulfate ion (SO4) is -2, so the oxidation number of Co must be +2 to balance the charges.
Cobalt tetraoxosulphate (vi) ion
Al(SO4)3 ^That is completely wrong. Al(SO4)3 is aluminum sulfate cobalt ii sulfide is CoS actually you both are wronq. its really CoSO4 <<< cobalt sulfate Wow. He/She was right. Your totally wrong. Cobalt (II) Co^2+ and Sulfide is S^2- So the answer is CoS. Signs cancel themselves out..
