How many milliliters of a 2000.0 mg/dl stock solution are needed to prepare 100.0 ml of a 150.0 mg/dl working solution?

  • Chemistry -

    Use the "dilution formula":
    V1C1 = V2C2
    V1, C1 = initial volume and concentration
    V2, C2 = final volume and concentration
    Your unknown is V1. Substitute the other which are given and solve for V1.
