Need help solving Pressure Vessel Calculation problem

[Greyfalcon]

Hello

I am a complete novice in pressure vessel calculation and I have to solve this problem given to me using whatever resources I can find on the internet. Now I spent last 2 days reading and watching various tutorials but I am still not able to solve the problem with the given data in the problem.
Given data:- Design a pressure vessel for CO2
Internal Pressure - 500 bar
ID - 500mm
Volume - 125 liters
Vessel Material - ss304
desired height - 5 to 7 feet

Every tutorial I found needed Temperature in order to find wall thickness and without finding wall thickness I cannot proceed any further. So can anyone please tell me how to find the temperature or whether I need to proceed without it somehow assuming some things.

Thank you

Are you sure you have the problem stated correctly? Maybe 500 mBars, instead?

500 bar does seem excessively high.
