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?

• chemistry -

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

20ml
