You need 76 mL of your stock silver acetate solution.
Diluting a solution decreases its molarity because you're essentially increasing the volume of the solution while keeping the number of moles of solute constant.
This means that you can work backwards from the target solution to determine what volume of the stock solution you need.
Use the molarity and volume of the target solution to determine how many moles of silver acetate are present
This means that you need the stock solution to contain 0.1525 moles of silver acetate, so you can determine its volume by
Expressed in mL and rounded to two sig figs, the answer will be
This is what the formula used for dilution calculations is all about. Here's how you'd solve using that approach
