Hydrogen peroxide is a chemical compound with the formula H2O2. In its pure form, it is a very pale blue liquid, slightly more viscous than water. Hydrogen peroxide is the simplest peroxide (a compound with an oxygen–oxygen single bond).

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.

The typical 3% hydrogen peroxide concentration found in stores can be used as a disinfectant, or you can dilute it to a 0.5% concentration, which still has some effectiveness, using a mixture of 2.5 parts water and 0.5 parts 3% hydrogen peroxide.

The calculation for oxygen is really similar. Again, there's two oxygens in the compound. So, there would be 31.998 grams per mole of oxygen in hydrogen peroxide. We divide that by the total mass of the compound, multiply it by 100%, and get the mass percent of oxygen in hydrogen peroxide being about 94%.

%O in water = 88.79% O. We went from chemical formula (H2O) to percent composition. We can also go from percent composition to the chemical formula.

Hydrogen Peroxide Two hydrogen (H) atoms can also bond with two oxygen (O) atoms, making the formula H2O2. That's just one more oxygen than water, 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.

The equation for percent composition is (mass of element/molecular mass) x 100. Find the molar mass of all the elements in the compound in grams per mole. Find the molecular mass of the entire compound. Divide the component's molar mass by the entire molecular mass.

Now, to know the percent composition of Carbon and Oxygen . We will divide their weight with the total weight of CO2. % C = 12.01/44.01 = 0.2729= 27.29% (we will divide 0.2729 with 100 to take the percentage).

Subtract to find the mass of oxygen in the compound. Divide each element's mass by the mass of the compound to find the percent by mass. Cancel units and calculate. Calculate the percent by mass of each element by dividing the mass of that element by the mass of the compound and multiplying by 100%.

DILUTION: To make a 3% solution: mix 11 ounces of distilled or reverse osmosis water with 1 ounce of 35% food grade hydrogen peroxide. ADDITIONAL USES FOR 35% H202 (Please note the difference between 35% solution hydrogen peroxide and 3% solution hydrogen peroxide.) minutes & rinse. This process prolongs freshness.
