What volume of a 2.5 M stock solution of acetic acid (HC2H3O2) is required to prepare 100.0 milliliters of a 0.50 M acetic acid solution?

    You don't need to do a balanced equation for this one. 2.5x =.100(.50)
    x=.020 this would be 20 ml
    the formula is Liters x Molarity =Moles
    so 2.5Molar times x # of liters =.100 x.50
    answer is 20ml

    20ml
