Hello.
We have made a Fe-Glycine and Fe-Salicylic Acid complexes in Lab.
There is a problem, after dehydration (letting it become dry in the air) , it becomes water insoluble.
Could you assist us?
What should we do?

In 0.25 liters of solution contains 2.3 gm of non-electrolite at 17°c and osmotic pressure is 488.2kPa. Find molecular weight of this non-electrolite solution.
