What will be the concentration of the solution obtained when 2500ml of water is added to a 37% v/v 1.19 g/ml (stock bottle)solution of hcl acid
I would point out that a 37% w/w solution has a density of 1.19 so I wonder if you have incorrectly labeled it as v/v.
It makes little difference which is true, if you don't give a volume of the hcl solution used there is no way to calculate the final concentration.
