We can use the formula C1V1 = C2V2 to solve the problem. C1 is the concentration of the stock solution (6.0 M) V1 is the volume of the stock solution we need to use (unknown) C2 is the desired concentration of the final solution (3.5 M) V2 is the final volume of the solution we want to make (0.25 L) Solving for V1: C1V1 = C2V2 (6.0 M) V1 = (3.5 M)(0.25 L) V1 = 0.1458 L = 145.8 mL Therefore, we need 146 mL of the 6.0 M HNO₃ solution to make 0.25 L of a 3.5 M HNO₃solution. The best choice is C.
