Nitric acid is a corrosive acid capable of dissolving many metals, with the evolution of brown nitrogen dioxide gas as a byproduct. It is often sold as concentrated nitric acid which has [HNO₃] = 16. M. A common concentration used in the laboratory is 6.0 M HNO₃. If you need 20. L of 6.0 M HNO₃, what volume of concentrated nitric acid is required?

Question

To find the volume of concentrated nitric acid needed, use the dilution formula: C1V1 = C2V2. Here, C1 = 16 M, C2 = 6.0 M, and V2 = 20 L. Solving for V1 gives V1 = (6.0 M * 20 L) / 16 M = 7.5 L.
