Tamic? At least you did not say "tannic".
I would only question what kind of concentration you mean, whether w/w or w/v or v/v. 7% solution is significant enough strength that density maybe be very important for the calculation. If the percents are v/v, then you simply can use
where x is liters of water to add.
