[poonilization]

Hello, i'm currently working on my final year project which is based on the advanced of MOF materials. I was reading a paper on MOF-5 and stumbled upon a pore volume value with the units cm³ cm^-3 which doesnt make sense as they would just cancel out. I assume i am misinterpreting the results, could someone elaborate as to why these are the untis?

Void volume / Total volume?

i.e. volume of cavity / gross volume of sample

Like imagine u drill a hole of dia. d through a cube of side 2d

You can divide volume of cylinderical hole by volume of entire cube.
