a student needs 25cm3 of 0.1 mol dm^-3 of ethanoic acid for an experiment. They are given a bottle of ethanoic acid with a concentration of 1 mol dm^-3. Calculate the volume of the ethanoic acid needed from the bottle and the volume of water to be added so as to get the correct volume and concentration for their experiment
