You want to prepare 500 ml of 1.0M acetic acid from a

17.4 M stock solution.What volume of stock
solution is required?

mlstock x Mstock = mLwaned x Mwanted

To determine the volume of the stock solution required, you can use the formula:

C1V1 = C2V2

Where:
C1 and V1 are the concentration (Molarity) and volume of the stock solution
C2 and V2 are the desired concentration and volume of the diluted solution

In this case, we want to prepare a 1.0 M acetic acid solution from a 17.4 M stock solution. And we know the desired volume is 500 ml.

Let's assume V1 is the volume of the stock solution required. So we have:

17.4 M * V1 = 1.0 M * 500 ml

Now we can solve for V1:

V1 = (1.0 M * 500 ml) / 17.4 M
V1 = 28.74 ml

Therefore, you would need approximately 28.74 ml of the 17.4 M stock solution to prepare 500 ml of 1.0 M acetic acid solution.
