Now you please tell the answer to your question since I am also interested to know the preparation of double Perovskites by soil-gel method.

You are most welcome dear Atul Kumar Agrawal

I guess it always involves mathematical formula's, but is it is not sam in every cane. For instance there is differenc between weight, volume, mol. weight based, etc. Question need further exploration.

I tell you. Is the calculation of chemicals your question?

If yes, then we can calculate via the unitary method.

If not satisfied then tell me further.

It seems that your question is old. So, Dr. S K Jaiswal must tell you.
