moving to misc.
if you know the exact amount in a container you could find its weight (density). then just find the density of given cncentrations in a book. and match it up with yours.

Nitric acid is generally sold at 68% to 70%. This would have a weight per milliter of 1.43 to 1.45 grams. Pure 100% acid has a specific gravity of 1.52. All you need is a accurate scale and an graduated cylinder to determine this.
