You might be able to estimate it based on the specific gravity. Knowing the specific gravity can tell you how similar it is to regular urine. You can then calculate from the difference the predicted change in the osmolarity of the material. This will be heavily biased towards the diet of the organisms the material came from.

Mattew thank you for your reply so do you know the equation which may use it in calculation?
