Question

How many molecules of hydrogen peroxide are in three molecules of hydrogen peroxide ?

Answer 1

Hydrogen Peroxide

Hydrogen PeroxideTwo hydrogen atoms can also bond with two oxygen (O) atoms (peroxide), making the formula H2O2. There is only one more oxygen atom than water (H2O) but it is a totally different compound. You can see that each of the oxygen atoms has eight electrons and the two hydrogens have two electrons each.

Answer 2

Answer:

H2O2 has 2 hydrogen atoms and 2 oxygen atoms in it. So one molecule of hydrogen peroxide weighs in at 34.02 u. The periodic table provides you with individual atomic masses. If you know the number and type of elements in a molecule you can add up the individual masses to find the molecular mass or molecular weight.
