Its possible i did a calculation wrong, so if you can find my mistake, then by all means do so.

alright, you have ur weight at a given pressure and you are stating that that weight is a constant, thats wrong my friend, temperature also plays a huge role in increasing pressure. The higher the temperature the more pressure the tank will contain. Since you didnt state what the temperature was, it was probably at a constant temperature such as 0 degrees celcius, or 32 degrees fahrenheit. As you probably know, nitrogen tanks are much hotter than 0 degrees celcius after a fill, you can actually feel the warmth, this means the temp inside the bottle is more than the constant temperature that you stated. Since the increase in temp increases the pressure, there is no need to increase the pressure by adding more gas. This means that your information about the weight is substantially more than the weight of an average fill.
