How many moles of O2 are in one mole of H3PO4?
Actually H3PO4 is a molecular formula referring to the compound we know as Phosphoric acid. It doesn't indicate number of moles of H3PO4. But the number of moles can be found out if the amount in mass or some other measurable quantity(e.g. conc. in solution) is given. The molar mass(mass of 1 mole) of H3PO4 is 98 grams. So if mass is given then it can be converted to grams and dividing by molar mass(i.e 98) we get number of moles. moles of H3PO4 =(mass of H3PO4 in grams)/98. 1 mole of H3PO4 has ->3 moles of H atoms. ->1 mole of P atoms. ->4 moles of O atoms. ( 1 mole=6.0225 *1023 units)

How do you balance out a chemical reaction?
first find out what the 'relative atomic mass' all the elements in the equation have. for example: __ KOH +____________________ H3PO4 → ______ K3PO4 + __ H2O k=39 O=16<-add them together(56)+H3(1x3) p=31 and O4=16x4 (and so on....) H= 1 anyway, continue doing that until you find out all the relative atomic masses, add each section together- so add what you get for KOH and H3PO4 but make sure that you don't add it on to K3PO4 and H2O because they're separate sections. after finsing out the score for each side, see which side has the highest number and
