how many hydrogen bonded water molecules are present in cu s o4 4.5 h2o?

Four water molecules are co-ordinated with Cu2+ and one is hydrogen bonded with SO42- in CuSO4.

3.50⋅mol×6.022×1023⋅mol−1≅21×1023 individual water molecules.

Figure 10.2. 1: Two water molecules contain 4 hydrogen atoms and 2 oxygen atoms. A mole of water molecules contains 2 moles of hydrogen atoms and 1 mole of oxygen atoms.

A water molecule consists of three atoms; an oxygen atom and two hydrogen atoms, which are bond together like little magnets.

Answer: The anhydrous salts of copper such as $$CuF_2$$ and $$CuSO_4$$ have white colour. This is because of the absence of water molecules (ligands), there is no splitting of d-orbitals in anhydrous copper salts. Hydrated copper sulphate (which contains 5 molecules of water) is blue in colour.

Therefore, the substance CuSO4•5H2O always consists of 90/250 or 36% water by weight. The water is a definite part of the structure of the compound, and the substance should not be considered to be “wet.” A few hydrated compounds lose water spontaneously to the atmosphere upon standing.

Is copper sulphate solid or aqueous? Copper(II) sulfate is a hydrated, blue solid – it is attached to water molecules. This becomes whitish when anhydrous – when it is not molecularly bound to water.

In 1 molecule of CuSO4 number of water molecule is 0 but in 1 molecule of hydrated copper sulphate 5 molecules of water are present.

Answer and Explanation: A water molecule can form four hydrogen bonds. Water is made up of two hydrogen atoms and an oxygen atom.
128667
Water is made up of two hydrogen (H) atoms and one oxygen (O) atom. The formula for water is H2O. The hydrogen atoms have filled orbitals with two electrons and the oxygen atom is filled with eight electrons.
331666
There are two atoms of hydrogen and one atom of oxygen in each water molecule, making the formula H2O. So, each molecule of water contains 3 atoms.

The mass ratio of CuSO4 : H2O is 4.00 : 2.25. To convert from mass ratio to mole ratio, you divide by the molecular mass of each 'species' CuSO4 = 64 + 32 + (4x18) = 160 and H2O = 1+1+16 = 18. The mole ratio of CuSO4 : H2O is 4.00/160 : 2.25/18.

A water molecule consists of two hydrogen atoms bonded to an oxygen atom, and its overall structure is bent.

The chemical formula for water is H2O which means that every molecule of water has 2 atoms of hydrogen (H) and one atom of oxygen (O).

The water of crystallization is the fixed number of water molecules present in one formula unit of a salt. Five water molecules are present in one formula unit of copper sulphate.

The standard answer is yes, because "H2SO4 is a strong acid, hence SO42− is a weak base. ... On its part, Cu2+ will strongly attract OH− groups, and overall protons will prevail over hydroxides."
