I'm still discovering electronics so bare with me...
Also, i'm not good at english.

I was looking for DC motor to be used on my project.
I saw a DC motor online and want to buy it.
It has a operating range of 3v-6v.

I was wondering..
Should i use that DC motor on 6v or should i use 2 of them on 3v at series connection?
What are the pros and cons for these??

Any leads would be helpful..

One motor or two? That depends more on what you plan to drive with them than on any electrical characteristics. If you need two rotating shafts then two motors might be useful. But why would you want to run them in series?

Would you be willing to share with the forum a few details about the project?  Like, for instance, how fast the motor(s) needs to run.  Or, does it need to run constantly or intermittently?  Or, how much load needs to be moved?  Or, how much torque will be needed.  Without hints like these no one will be able to give you an intelligent response.

Have a look at this: https://forum.arduino.cc/index.php?topic=149020.0

The voltage mentioned for a motor is only a small part of its specification and is not sufficient to decide whether a motor is suitable.

It is entirely possible to get a 3v motor that is a great deal more powerful than a 6 volt motor.

For a given motor driving it with a higher voltage will force more current through it resulting in more torque and power. However higher currents lead to overheating and the risk of the motor failing.

No idea, you haven't said what you want to do with motor(s).  For a given motor a higher
voltage will give a higher top speed, and a higher stall current.
