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)
What else can I help you with?
How many moles of hydrogen atoms are in one mole of phosphoric acid?
One mole of phosphoric acid (H3PO4) contains three moles of hydrogen atoms. This is because there are three hydrogen atoms in each molecule of phosphoric acid. Each mole of phosphoric acid contributes three moles of hydrogen atoms to the overall chemical formula.
How many moles of H are there in 2.1 moles of H3PO4?
We have 2.1 moles of H3PO4 However , there are three hydrogen atoms. So this makes for 3 x 2.1 = 6.3 moles of hydrogen atoms. Further, hydrogen exists as the diatomic molecule 'H2'. So a 'free' hydrogen molecules of H2 we have 6.3 / 2 = 3.15 moles(H2)
How many moles of oxygen are there in one mole of hydrogen peroxide?
In one mole of hydrogen peroxide (H2O2), there are two moles of oxygen atoms.
How many moles of Na plus ions are there in a moles of NaCl?
There is one mole of Na⁺ ions for every mole of NaCl. This is because each mole of NaCl dissociates into one mole of Na⁺ ions and one mole of Cl⁻ ions in solution.

How many moles of Fe and S are contained in one mole of FeS2?
the atomic mass of FeS2 is 110. You cannot find the no. of moles in a mole of FeS2 coz it is only a mole.
How many moles of iodine are in one mole?
There is one mole of iodine in one mole. There are 126.90447grams of iodine in one mole. There are also 6.022x1023 atoms in one mole.
How many moles are in 100g of H2PO4?
One molecule of P2O3 = 1 mole. Go to the periodic table P = 30gm x 2 = 60 gm. O= 16 gm x 3 = 48 mg. Total is 60 + 48 = 108 gm is the weight of one molecule which is also the number of grams in 1 mole (remember 1 mol = 1 mole). So since you have 37.9 grams divide this by 108 and you have .35 moles.
