If you need to make a solution of 1.0L at 2.5M citric acid and you only have 45mL of 5.0M citric acid, do you have enough for your experiment?

If a mathematical procedure is involved, please explain to me; I really want to grasp this chemistry concept.

you want to dilute it 5/2.5=2 times, which means one part stock, one part water.

what is one part? 1liter/2parts=500ml

so you don't have enough acid to make one part, therefore, you cannot make one liter of diluted acid.
