What is the molarity of a solution prepared by diluting 25 mL of 1.2 molar H₂SO₄ to 1.0 L?

Molarity is defined as moles of solute per liter of solution. In this problem, we have 25 mL (0.025 L) of 1.2 M H₂SO₄. To dilute this solution to 1.0 L, we add (1.0 L - 0.025 L) = 0.975 L of solvent (likely water). The moles of solute should remain constant before and after dilution. We can use the formula: M1V1 = M2V2 where M1 is the initial molarity, V1 is the initial volume, M2 is the final molarity, and V2 is the final volume. Plugging in values, we have: (1.2 M) (0.025 L) = M2 (1.0 L) M2 = 0.030 M Therefore, the solution has a molarity of 0.030 M after dilution. The correct choice is (C).
