Answer:
585ml
Explanation:
13 fold means that volume of the diluted solution is 13 times higher than the volume of the stock.
It means you have to perform 1:13 dilution
D f = Vdiluted/ Vstock
Vdiluted = 13 × Vstock
Vdiluted = 13 × 45ml
Vdiluted = 585ml
You will need to add enough water to the stock (MgSO4) solution till it gets to a total volume of 585ml
