How many moles are in 7.36 x 1025 molecules of H2O?

There are 122.1982401 moles of  H2O in  molecules of H2O

Explanation:

We know,

 molecules of H2O contains 1 mole H2O

            1      molecules of H2O contains  mole H2O

∴ molecules of H2O contains moles of H2O

                                                               = 122.1982401 moles of  H2O

∴ There are 122.1982401 moles of  H2O in  molecules of H2O
