Molarity Quiz 5

Molarity is a key concept in chemistry, defined as the concentration of a solute in a solution, expressed in moles per liter (mol/L). It helps quantify how much solute is present in a given volume of solution, essential for reactions, solution preparation, and titrations. Understanding molarity is crucial for accurate chemical calculations and laboratory applications.

1) A solution is prepared by mixing 1 L of a 0.5 M NaOH solution with 500 mL of a 1 M NaOH solution. What is the molarity of the resulting solution?

2 / 5

2) A 2.5 M solution of sulfuric acid (H₂SO₄) needs to be diluted to 1 M. If the initial volume is 200 mL, what should be the final volume of the solution?
