It is not that simple in determining gain.  There are several factors to consider, have a look at this website.  It shows different formulas depending on configuration of the circuit:


and the components used.

Here are the data sheets for the two devices:



They are both general purpose op amps.
The 741 uses bipolar transistors, and it is quite an old design.
The 3130 uses a combination of MOS and bipolar transistors.  It is much newer and quite a bit faster.  And it has a smaller usable power supply range, so they are certainly not interchangeable in all cases.

I don't know what you mean by gain formula.  Depending on the details of your application,
you may be able to use one, either, or neither of these parts.
