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?

Answer 1

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

Answer 2

20ml

Answer 3

How would you put it into a equation

Answer 4

0.020 liters is the correct answer
