How to determine component content given specific gravity

The solubility of solute A in water is very high; how can the concentration of each solute be determined using their respective specific gravities? Thank you for your discussions!! Special note: It is assumed that there are changes in volume before and after mixing, so volume changes cannot be ignored!

It is difficult to calculate accurately; only estimation is possible, or it can be determined through experimentation
The volume change before and after dissolution is easy to measure. It would be best for the original poster to conduct actual measurements, so as to avoid large errors in estimation
Is it possible to prepare mixtures of different concentrations by oneself, create a curve showing the relationship between density and concentration, and then refer to this curve for quick reference when using them? I’ve tried this before, and it’s quite accurate
