answered-by-expert Expert Answer

amount of acid will remain same in both the solution , but its % changes

initially amount of acid = 1125*0.45

let x L water is added then its acid % will be (1125*0.45) / (1125+x)

it should lie between 25% to 30%

.25 (1125*0.45) / (1125+x) .3

on solving this we get 562.5 x 900
