Phosphoric acid- 3H3PO4
In just one molecule there is three hydrogens' (H3), one phosphorous (P), and four oxygens (O4). This is a total of eight atoms in one molecule. But since there are three molecules (due to the '3' in front), you triple the number of atoms in one molecule of phosphoric acid; to a total of 24.
each mol of h3po4 has 6.022*10^23 molecules you have 1.5 mol, so 1.5 * 6.022*10^23 molecules = 9.033*10^23 molecules each molecule of h3po4 has 1 atom of p, so you have 9.033*10^23 atoms p.
The number of atoms of each element present in a molecule is indicated by the subscript to the right of the element symbol in the chemical formula. For example, in H2O, there are 2 hydrogen atoms and 1 oxygen atom.
This is specified by the subscripted number directly next right-down to the atom's symbol.Example: Sulfuric acid: H2SO4 has 2 atoms of Hydrogen, 1 atom of Sulfur and 4 atoms of Oxygen per molecule H2SO4
The name of the compound dinitrogen tetrahydride implies that the formula of the compound is N2H4. Therefore, each molecule contains two nitrogen atoms and four hydrogen atoms.
The formula is H3PO4 O | HO-P-OH | OH O HO-P-OH H3PO4 OH
As 1 molecule of H3PO4 contains 3 hydrogen atoms, 4.56x1023 contain 3x(4.56x1023) hydrogen atoms.
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.
There are 6 hydrogen atoms, 3 phosphorus atoms, and 4 oxygen atoms in the formula H3PO4.
each mol of h3po4 has 6.022*10^23 molecules you have 1.5 mol, so 1.5 * 6.022*10^23 molecules = 9.033*10^23 molecules each molecule of h3po4 has 1 atom of p, so you have 9.033*10^23 atoms p.
The chemical formula shows you this. The subscripted number next to each element shows how many atoms are present in a molecule or formula unit. If no number is shown, then only one atom of that element is present.
The number of atoms of each element present in a molecule is indicated by the subscript to the right of the element symbol in the chemical formula. For example, in H2O, there are 2 hydrogen atoms and 1 oxygen atom.
Water molecule (H2O) has 2 hydrogen atoms and 1 oxygen atom.
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.
NH3; One atom of nitrogen and three atoms of hydrogen.
In each molecule of NO3, there is one nitrogen atom and there are three oxygen atoms.
To balance the reaction between H3PO4 and NaOH, first write out the chemical equation: H3PO4 + 3 NaOH -> Na3PO4 + 3 H2O Now, each element must have the same number of atoms on both sides of the equation for it to be balanced. Adjust the coefficients in front of each compound to achieve this balance.
At standard temperature and pressure, nitrogen exists in molecules with two atoms each.
