Apply the mole concept to calculate moles of solute, concentratio n and volume of a solution. (Formula: Molarity/Concentration (c) = moles of solute ( n) volume of solution (V)) Identifying ions in solution

A 25.0 mL aliquot of aqueous sulfuric acid (H₂SO₄) with a concentration of 0.200 mol L⁻¹ was diluted with 475.0 mL of water to make a final volume of 500.0 mL. Calculate the concentration of H⁺ ions in the final solution.

A 25.0 mL aliquot of 0.150 M sulfuric acid (H₂SO₄) solution was diluted with water to a final volume of 250.0 mL. What is the concentration of sulfate ions (SO₄²⁻) in the diluted solution?

A student prepares a solution by dissolving 8.5 g of sodium chloride (NaCl) in water and diluting to a final volume of 500 mL. (Relative atomic masses: Na = 23, Cl = 35.5) (a) Calculate the number of moles of NaCl dissolved. [1] (b) Calculate the concentration of the sodium chloride solution in mol/L. [1]
