The molar concentration of Na⁺ ions In 0.0200 M solutions of the given sodium salts in water is:
For NaBr, the molar concentration of Na⁺ ions = 0.020 M
For Na₂SO₄; the molar concentration of Na⁺ ions = 0.040 M
For Na₃PO₄; the molar concentration of Na⁺ ions = 0.060 M
The molar concentration of a substance is the amount in moles of that substance that is present in a given volume of a solution of that substance.
Mathematically;
The molar concentration of Na⁺ ions In 0.0200 M solutions of the given sodium salts in water is calculated as follows:
Molar concentration = moles of sodium ions in 1 mole of the salt * molar concentration of the salt.
For NaBr;
moles of Na⁺ ions in 1 mole of the salt = 1 mole
molar concentration of Na⁺ ions = 1 * 0.020 M
molar concentration of Na⁺ ions = 0.020 M
For Na₂SO₄;
moles of Na⁺ ions in 1 mole of the salt = 2 moles
molar concentration of Na⁺ ions = 2 * 0.020 M
the molar concentration of Na⁺ ions = 0.040 M
For Na₃PO₄;
moles of Na⁺ ions in 1 mole of the salt = 3 moles
molar concentration of Na⁺ ions = 3 * 0.020 M
the molar concentration of Na⁺ ions = 0.060 M
