how many ml of water are present in 250ml of a 15% by volume oguous hydrocloric acid solution?

15% w/v means 15 g solute in 100 mL solution.
[(x g solute)/250 mL] = 0.15
x g solute = 250 x 0.15 = 37.5g HCl

Therefore,
(37.5g HCl)/(mL HCl + mL H2O) = 0.15
Since mL HCl + mL H2O = 250, you can solve for mL H2O if you know the volume occupied by 37.5g HCl. There is no date in your problem to show that or to allow us to calcluate it.
