get the moles of hydrogen ions present in the solution by writing down the acid dissociation formula of the acid. Find the concentration of hydrogen ions present in the solution. Use -log[H+] to get the pH.
How do you indicate oxygen?
You indicate oxygen when writing by using the word oxygenor the symbol "O". If you are dealing with the oxygen molecule, you might write O2.There are many ways to test for the presence of oxygen, but which is appropriate depends on whether oxygen is present as a gas or as part of a more complex compound, whether as a gas, a liquid or a solid..

What is the proper way of writing the chemical formula?
There are many ways to write a chemical formula, but the most common way is by following these steps (beware that different types of bonding are named in different ways) 1) Look at the charges for all listed elements or polyatomic ions and solve for neutrality (in other words, make sure that when you multiply the charges by the number of each and then add them together so it equals zero) 2) You may not have to look at the charges if it is a type IV compound in which case you can look at the greek prefixes and use those to figure out how much of each you need (just for reference: mono=1 but it is rarely used) di=2 (sometimes bi) tri=3 tetra=4 (sometimes cuad) penta=5 hexa=6 hepta=7 (sometimes septa) octa=8 nona=9... and the list continues 3) Lastly, just write out the formula with the more electronegative element or polyatomic ion first(if you have the name the more electronegative one will be the element listed first) and using subscript(s), indicate the number of each part
