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  ...

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). Here comes the key part. From the Periodic Table of Elements, one sees that one mole of hydrogen atoms weighs 1 gram while one mole of oxygen atoms weighs 16 grams. What is  ...

0.450 mole (or gram) of Fe contains how many atoms? 0.200 mole (or gram) of H 2O contains how many molecules? When the word gram replaces mole, you have a related set of problems which requires one more step. So keep in mind that there are 4 example problems just above. Calculate the number of molecules in ...
