Calculating Hydrogen Mass Storage in Compressed Vessels

[Brool]

Hello all;

I am looking for an equation for calculating mass storage of Hydrogen in compressed vessels
I have fount the following link (https://nanosun.co.uk/hydrogen-tools) which provides what i need but would like to create something similar for internal use

Can you suggest an approach to this?

Regards;
Haim

Are you familiar with the concept of compressibility factor z?

hi Chester,

to some level.

hi Chester,

to some level.

Then you know how to calculate the mass, given the volume, temperature, and pressure? Also, are you familiar with other equations of state, like van der Waals?
