M5L2A Percent Composition Cartoon

I wonder if there is a way to figure out the percent composition by mass
Yes, I would like to figure out whether or not that is possible
Water has two hydrogen molecule and one oxygen molecule, thus the name H2O. Using both the hydrogen and oxygen masses, we can figure out the molar mass of water.
"Alright class listen up and pay attention."
In Chemistry, there is a way to figure out the percent composition. However the first step begins with finding the mass of the elements inside the compound such as the more famous H2O that is being measured.
H2O consists of two masses, hydrogen and oxygen. Hydrogen has an Atomic Weight of 1.00794 while Oxygen has an Atomic Weight of 15.9994. When combined together, you get a molar mass of 18.01528 g/moles.
There is a few things to pay close attention to when finding the percentage. The equation is: (Mass / Molar Mass) * 100. So for Oxygen it would be (15.9994 / 18.01528)*100 to get 88%. For Hydrogen it would be (1.00794 / 18.01528)* 100 to get twelve. This proves that water consists of 12% Hydrogen and 88% Oxygen.
