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 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 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 atoms of H are containedin 4.56x1020 molecules of H3PO4?
As 1 molecule of H3PO4 contains 3 hydrogen atoms, 4.56x1023 contain 3x(4.56x1023) hydrogen atoms.
What is Ka for H3PO4(aq) H (aq) H2PO4-(aq)?
Since H3PO4 has 3 ionizable hydrogens, it will have three Ka values. Approximate values areKa1 = 7x10^-3; Ka2 = 6x10^-8 and Ka3 = 4.5x10^-13
The chemical equation that shows the dissociation of 2 protons from trihydrogen phosphate?
The dissociation of 2 protons from trihydrogen phosphate (H3PO4) results in the formation of dihydrogen phosphate (H2PO4-) and a water molecule (H2O). The chemical equation for this process can be written as: H3PO4 ⇌ H2PO4- + H+ + H2O

How many moles of co2 will be produced if 5.31 moles of c4h10 are used?
The combustion of butane (C₄H₁₀) can be represented by the balanced equation: 2 C₄H₁₀ + 13 O₂ → 8 CO₂ + 10 H₂O. From this equation, we see that 2 moles of butane produce 8 moles of carbon dioxide. Therefore, if 5.31 moles of C₄H₁₀ are used, the moles of CO₂ produced can be calculated as follows: (5.31 moles C₄H₁₀) × (8 moles CO₂ / 2 moles C₄H₁₀) = 21.24 moles of CO₂.
