- Add some significant amount of water to an empty volumetric flask capable of measuring 250.0 mL. - Put 6.94 mL of the $18.0$ $M$ sulfuric acid solution in the flask, using a pipet. - Fill the recipient with sufficient water to reach the 250.0 mL mark.
Work Step by Step
1. Find the volume necessary: $C_1 * V_1 = C_2 * V_2$ $ 0.500* 250.0= 18.0 * V_2$ $ 125 = 18 * V_2$ $V_2 = 6.94$ $mL$
