The molar mass of phosphoric acid is 98.0 g/mol. Calculate moles of each element: H = 0.3078/1.007 = 0.3054 mol; P = 3.161/30.974 = 0.1021 mol; O = (6.531 - 0.3086 - 3.161) / 16 = 0.162 mol. Divide moles by the smallest value to get the empirical formula ratio: H1P1O4, which simplifies to H3PO4.

Is phosphoric acid organic?
Phosphoric acid is a mineral acid and is not considered organic. It is typically produced from inorganic sources such as phosphorus minerals or by treating phosphorus compounds.
What do phosphoric acid and iron make?
When phosphoric acid reacts with iron, it produces iron(III) phosphate and hydrogen gas. This reaction is represented by the chemical equation: 3H3PO4 + Fe → FePO4 + 3H2.
What is the relative atomic mass of phosphoric acid?
The relative atomic mass of phosphoric acid (H3PO4) is calculated by adding the atomic masses of all the constituent atoms. Phosphoric acid contains one phosphorus atom with an atomic mass of approximately 31.0, three hydrogen atoms with an atomic mass of approximately 1.0 each, and four oxygen atoms with an atomic mass of approximately 16.0 each. Adding these together gives an approximate relative atomic mass of 98.0.
What is the empirical number for water?
The empirical formula for water is H2O, indicating that water is composed of two hydrogen atoms for every oxygen atom.
What are compounds that contain hydrogen and oxygen?
There are many compounds with oxygen and hydrogen. The most trivial is water, H2O. Also, every acid contains hydrogen, and if they contains oxygen too, they are oxo-acids. Examples: Hydrogen-peroxide: H2O2 Halogenide oxo-acids: HOF HOCl HOBr HOI Sulphuric acid, H2SO4, and sulphite acid, H2SO3. Nitric acid, HNO3, and nitrous acid, HNO2. Phosphoric acids: H4P2O7, H3PO3, H3PO4. Also, there is a lot of organic oxo acids. Every alcohol contains oxygen and hydrogen, every phenol, aether, carbohydrate contains them too.
Does phosphoric acid contain phosphate?
Yes, phosphoric acid contains phosphate ions. It is a mineral acid composed of phosphorus, oxygen, and hydrogen. When it dissolves in water, phosphoric acid releases phosphate ions.
How many atoms in phosphoric acid?
Phosphoric acid (H3PO4) contains 5 atoms: 3 atoms of hydrogen, 1 atom of phosphorus, and 4 atoms of oxygen.
Is phosphorous acid an element?
The empirical formula for phosphoric acid is H3PO4. Its molecular formula is P2O5·3H2O. It is composed of the elements hydrogen, phosphorus and oxygen. Most solutions of phosphoric acid are composed of some amount of H3PO4 in water, H2O.For more information about phosphoric acid, see the Web Links to the left.
What is the empirical formula of a substance that contains 0.117 of carbon 0.233 of hydrogen and 0.117 of oxygen?
The molar ratios of carbon, hydrogen, and oxygen atoms are 1:2:1, so the empirical formula is CH₂O.
What is 2h3po4?
2H3PO4 refers to two molecules of phosphoric acid. Each molecule of phosphoric acid (H3PO4) contains one phosphorus atom, three oxygen atoms, and four hydrogen atoms.
What is the arrangement of phosphoric acid?
H3PO4 (3 hydrogen 4 phosphoric oxygen)
What is the empirical formula for water?
The empirical formula for water is H2O, indicating that each molecule of water contains 2 hydrogen atoms and 1 oxygen atom.
Combustion analysis of toluene a common organic solvent gives 5.86 mg of CO2 and 1.37 mg of H2O If the compound contains only carbon and hydrogen what is its empirical formula?
To find the empirical formula, we first need to convert the mass of CO2 and H2O to moles. From the molar ratios in the products, we find the moles of carbon and hydrogen present. Then, we determine the ratio of carbon to hydrogen atoms, giving the empirical formula as C7H8.
The empirical formula for acetylene?
The empirical formula for acetylene is C2H2, which indicates that one molecule of acetylene contains two carbon atoms and two hydrogen atoms.
What is the formula for H3PO4?
The chemical formula for phosphoric acid (H3PO4) consists of one phosphorus atom, four oxygen atoms, and three hydrogen atoms.
Is phosphoric acid organic?
Phosphoric acid is a mineral acid and is not considered organic. It is typically produced from inorganic sources such as phosphorus minerals or by treating phosphorus compounds.
What is the product of phosphoric acid and hydrogen?
When hydrogen reacts with phosphoric acid, it forms dihydrogen phosphate, which is the conjugate base of phosphoric acid. The chemical equation for this reaction is: H3PO4 + H2 → H3PO4- + H2.
