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

in 1783 cavendish was working with his hydrogen gas and found that when he burned it and condensed the vapor it was water. this was very significant since it disproved the greek theory of elements completely since water was not a simple substance but the product of two gases. it was lavoisier who hearing of the experiment gave cavendish's gas the name hydrogen ("water-producer") and added that hydrogen burned by combining with oxygen and that water was a hydrogen-oxygen combination.
