A mole refers to 6.022⋅1023 items. H2O has 2 hydrogen atoms and 1 oxygen atom...so a total of 3 atoms in each H2O . Therefore (6.022⋅1023)⋅ (3 atoms) = 18.066⋅1023. Then we need to change the answer into proper scientific notation : 18.066⋅1023=1.8066⋅1024. Lastly, change to the proper number of significant  ...
