To dilute 6% hydrogen peroxide to 19%, you would need to mix the 6% hydrogen peroxide with a calculated amount of water. To do this, you can use the formula C1V1 = C2V2, where C1 is the initial concentration (6%), V1 is the volume of the initial solution, C2 is the final concentration (19%), and V2 is the final volume of the solution. By rearranging the formula, you can calculate the volume of 6% hydrogen peroxide needed and then add the appropriate amount of water to achieve the desired 19% concentration. **
