Depending on your model, 4GB(DDR), 8GB(DDR), or 16GB(DDR2) What is the processor speed/configuration for it? (What's it's processor speed, and how many cores does it have?) And yes, you can install Mac OS Leopard on this computer.

Go here for your max RAM config. Your machine will take 10.5.8 max.
Can you install Mojave 10.8 on a G5?

Sadly no, The PowerPC CPU is not able to run any of the Intel versions of macOS. The highest version it can support is OS-X Leopard (10.5.8)
The case is a marvel of engineering when Apple was thinking straight! The Mac Pro carried it forward and the latest version of Mac Pro holds true to its design principles.
Many people have converted their G5's to Intel boxes using ATX logic board PowerMac G5—ATX Conversion Build Log and even hacked MacOS to run on it as well! A bit of a reverse Hackintosh! Mac PowerPC > Intel CPU upgrade > Mac Intel OS.
