It would be nice to have a few more details such as what you are working on. With limited details I will guess that your float/sending unit in the tank is malfunctioning. A second possibility is a bad fuel gauge if it is mechanical.
Failed gauge, wiring, or level sensor.
The most common reason for the fuel gauge in an Impala to stop at half full is a bad fuel sensor. The sensor is mounted inside of the fuel tank.
Yes, a tank of oxygen can be half full. The oxygen would be stuck in said tank meaning no more oxygen can get in unless refueld.
For long term storage, keep it full.

well if you are an optimist you could say 'The tank is half full'.
no it should not be half full, it should be 80-90% full with the void space pressurized by or with air
It is not - I just checked and is is nearly 80% full.
96 litres.
No problem.
take 16 times whatever half a tank is
A faulty fuel gauge sending unit.
