The specific heat of water is 4.18 j/(g⋅∘c). calculate the molar heat capacity of water. express your answer to three significant figures and include the appropriate units.

Explanation:

It is known that relation between specific heat and molar heat capacity is as follows.

             Molar specific heat = Specific heat × Molar mass

It is given that specific heat of water is 4.18 . Now, we will calculate the molar mass water as follows.

      Molar mass of oxygen = 15.99 g/mol

      Molar mass of = g/mol = 2.00 g.mol

Hence, molar mass of = (15.99 + 2.00) g/mol

                                                    = 17.99 g/mol

Therefore, calculate the molar specific heat of water as follows.

              Molar specific heat = Specific heat × Molar mass

                                               =

                                               = 75.2    

Thus, we can conclude that the molar heat capacity of water is 75.2 .

convalent bond :

is a chemical bond formed by the sharing of electron between 2 atoms.

it is the direct chemical bond between 2 atoms.

in bond formation atoms are involved here.

electrovalent bond:

is a chemical bond defined as electroststic attraction between 2 atoms.

it is the electrostatic attraction between 2 atoms.

in bond formation, ions are involved here.

the number of valence electrons for each molecule or ion is shown beneath the structure. remember hydrogen will not have more than two electrons. this hydrogen is part of a covalent bond (sharing two electrons). a double bond here would cause hydrogen to share four electrons with phosphorus.
