3 moles of sodium and 1 mole of phosphate
The molarity of Na+ ions in a 0.25 M solution of Na3PO4 is 0.75 M. This is because each formula unit of Na3PO4 dissociates into 3 Na+ ions in solution. Therefore, the concentration of Na+ ions is three times the molarity of the Na3PO4 solution.
The chemical formula for sodium phosphate is Na3PO4, which exists as a solid white powder at room temperature
The oxidation state of phosphorus in the phosphate ion (PO43-) is +5. This is because each oxygen atom has an oxidation state of -2, and the overall charge of the ion is -3, so the phosphorus must have an oxidation state of +5 to balance the charges.
The charge for Na3PO4 is -1. This is because each sodium ion (Na+) has a charge of +1 and each phosphate ion (PO4 3-) has a charge of -3. By combining three sodium ions with one phosphate ion, the overall charge of the compound becomes -1.
There are 5 moles of sulfur in 5 moles of H2SO4, as there is 1 mole of sulfur in each mole of H2SO4.
There are 0.75 moles of sodium ions present in 2.50 L of 0.300 M Na3PO4. Each formula unit of Na3PO4 has 3 sodium ions. So, for every mole of Na3PO4, there are 3 moles of sodium ions. Calculating the moles of sodium ions: 2.5 L * 0.300 mol/L * 3 mol Na+ / 1 mol Na3PO4 = 0.75 moles of Na+.
To determine which solution contains the largest number of ions, we need to calculate the total moles of ions produced by each solution. NaOH (100ml of 0.1M): 0.1 moles/L × 0.1 L = 0.01 moles of NaOH → produces 0.01 moles Na⁺ and 0.01 moles OH⁻ = 0.02 moles of ions. BaCl2 (50ml of 0.2M): 0.2 moles/L × 0.05 L = 0.01 moles of BaCl2 → produces 0.01 moles Ba²⁺ and 0.02 moles Cl⁻ = 0.03 moles of ions. Na3PO4 (75ml of 0.15M): 0.15 moles/L × 0.075 L = 0.01125 moles of Na3PO4 → produces 0.03375 moles Na⁺ and 0.01125 moles PO4³⁻ = 0.045 moles of ions. Therefore, Na3PO4 contains the largest number of ions.
There are 7.05 moles of oxygen atoms in 2.35 moles of sodium phosphate, as there are 3 oxygen atoms in each formula unit of sodium phosphate (Na3PO4).
The molarity of Na+ ions in a 0.25 M solution of Na3PO4 is 0.75 M. This is because each formula unit of Na3PO4 dissociates into 3 Na+ ions in solution. Therefore, the concentration of Na+ ions is three times the molarity of the Na3PO4 solution.
The chemical formula for sodium phosphate is Na3PO4, which indicates that each molecule of sodium phosphate contains three sodium ions (Na+) and one phosphate ion (PO4^3-).

3,7 moles of C8H11NO2 have 3,7 moles of oxygen (O2).
There are 9.12 moles of hydrogen atoms in 4.56 moles of NH2NH2. Each NH2NH2 molecule contains 2 hydrogen atoms.
The formula PO43- indicates that the ion is composed of one phosphorus atom bonded to four oxygen atoms with a total charge of -3. Each oxygen atom contributes two electrons to the bond, while the phosphorus atom contributes five electrons.
