Now, likewise, I multiply 100 grams times 0.8
889. This gives me 88.89 grams of oxygen in my 100 grams of compound. Now I have to convert my grams to moles. In other words, I want to find how many moles of each guy of each atom is in my compound. Now, eleven point 11 grams of h divided by the molecular or atomic weight of h 1 gram/mol gives me eleven point eleven moles of h.
Likewise, I do the same thing for oxygen. 88.89 grams of oxygen divided by the atomic weight for oxygen 16 grams/mol grams cancel and I get 5.56
mole.
