Michael A. McKibben

The relationship between mass (g) and volume (cm3) is density, so you need to know the density (g/cm3) of the mineral phase you are considering.

Mahdi Shayan Nasr

Thank you very much dear @Michael A. McKibben for your reply, I have already done this for a mineral, but I got a strange amount after conversion.

Yuri Mirgorod

If you received a strange amount, then this is already a discovery for you. In order for the RG robot to send your answer to the consultant, you need to click on Mention.

Thank you dear Yuri Mirgorod
