Yes. As I posted elsewhere in another thread.
Caswell LCD 3:1 solution is about 1.075 specific gravity
the od method 2:1 solution is about 1.100

Search the other threads for my posts. I have a lot more info supporting this there.
I do point out that specific gravity doesn't change too much for normal anodizing solutions but it's a simple way to get on track as to what your solution might be.
