How to find a device with the serial number

You cannot. There is no function or method to finding a device using the serial number for it.

To Find the Device, you need to log in to the Apple ID it is using, and use the Find My app to track it.

You cannot find or trace an iOS/iPadOS device using the Serial Number alone.

Here is Apple’s advice for lost or stolen devices:

If your iPhone, iPad or iPod touch is lost or stolen – Apple Support

Use the Find My app to locate a lost or stolen device – Apple Support

If the Find My iPad feature was enabled prior to it being “misplaced”, then if active, you would stand a good chance of locating it. 

However, if the feature was not activated prior to being misplaced - or the iPad has been inactive for more than 24 hours, the last known location will not be available - and the opportunity to use technical means to recover the iPad have been lost.

Find it how/where? If it is lost or stolen - no, you can’t.
