Take a known weight of the sodium carbonate, heat it to above 100ºC to drive off the water, and keep heating until a constant weight is obtained. The difference between initial weight and final weight is the mass of water attached. Convert this to moles and then to molecules and relate this to 1 formula unit of Na2CO3.
Sodium carbonate: Na2CO3.10H2OMagnesium sulfate: MgSO4.7H2OCopper (II) sulfate: CuSO4.xH2O, where x = 1-5
A carbon carbonate don't exist. Thew ion carbonate is CO3-; a metal carbonate has the chemical formula MeCO3.
The formula for manganese carbonate is MnCO3.
The formula for plumbic carbonate is PbCO3. So there is one carbonate ion (CO3)-2 in the unit formula for PbCO3. A more modern name for this compound is lead (II) carbonate.
The correct formula for iron(III) carbonate hexahydrate is Fe2(CO3)3·6H2O. This compound consists of two iron(III) ions, three carbonate ions, and six water molecules. Iron(III) indicates the +3 oxidation state of iron, while the hexahydrate designation signifies the presence of six water molecules associated with the compound.
In the formula 2CaCO3, there are 2 molecules of calcium carbonate (CaCO3) in total. Each molecule of calcium carbonate consists of one calcium atom, one carbon atom, and three oxygen atoms.
The formula K2CO3.2H2O represents potassium carbonate dihydrate. It consists of two potassium (K) ions, one carbonate (CO3) ion, and two water (H2O) molecules.

Rb2CO3 for rubidium carbonate
The formula of sodium [note correct spelling] carbonate is Na2CO3.
A carbon carbonate don't exist. Thew ion carbonate is CO3-; a metal carbonate has the chemical formula MeCO3.
The formula for Vanadium (IV) carbonate is V(CO3)2.
The chemical formula of calcium carbonate is CaCO3.
The formula for dinitrogen carbonate is N2CO3.
The formula for manganese carbonate is MnCO3.
Ammonia and carbonate do not make a formula, they make a compound which is ammonium carbonate,
Sodium dihydrogen carbonate is not a proper chemical name and therefore has no formula, because carbonate anions have only two negative charges and therefore can not form a neutral compound with one sodium atom and two hydrogen atoms. The closest analogous compound is sodium hydrogen carbonate, which has the formula NaHCO3.
