Question

anonymous · Answer

is this not the same concept as before? what chapter are you on ?

anonymous · Answer

Chapter 4 and you are probably right.

anonymous · Answer

Chapter 4 being over stoichiometry

You're taking a small amount of something very concentrated, and adding water to dilute it to a larger volume, but a lower concentration. The equation that is useful here is :$$M{_C}*V{_C} = M{_D}*V{_D}$$ where C is the concentrated form, and D is the dilute form. You have 3 of these 4 values given in the problem, plug in and solve.
