These compounds are called hydrates. Copper(II) sulfate pentahydrate is an example of such a hydrate. Its formula is CuSO4 5H2O. The five in front of the formula for water tells us there are 5 water molecules per formula unit of CuSO4 (or 5 moles of water per mole of CuSO4).

Formula of a Hydrate (Anhydrous Solid⋅xH2O) In order to determine the formula of the hydrate, [Anhydrous Solid⋅xH2O], the number of moles of water per mole of anhydrous solid (x) will be calculated by dividing the number of moles of water by the number of moles of the anhydrous solid (Equation 2.12.

H5O2+ may be fully hydrated, with an equally spaced or unequally spaced central hydrogen bond, with one water molecule hydrogen-bonded to the four free hydrogen atoms as H13O6+ (the Stoyanov ion [2134, 2135]). The unit positive excess charge is thus spread out over at least 13 hydrogen atoms.

Water has a molar mass of 18.01528 g/mol≈18 g/mol . Since water has a chemical formula of H2O , there will be 2 moles of hydrogen in every mole of water. In one mole of water, there will exist approximately 6.02⋅1023 water molecules. So, there will be a total of 6.02⋅1023⋅2≈1.2⋅1024 hydrogen atoms.

Its formula is CuSO4 5H2O. The five in front of the formula for water tells us there are 5 water molecules per formula unit of CuSO4 (or 5 moles of water per mole of CuSO4). The water in the formula is referred to as the water of hydration, and the dot indicates that the water is chemically bonded to the CuSO4 salt.

The molecular formula H2O2 is a multiple of the empirical formula. We can know this because the ratio of 2H:2O is not the lowest whole number ratio. By dividing the subscripts by 2 , we can determine the lowest whole number ratio, which is 1H:1O . Therefore, the empirical formula for H2O2 is HO .
