Hello every one, respected researcher help me how to find theoretical density of a hydrated salt in GJ/m3?

17 October 2017 1 8K Report

i am confused to find out theoretical energy density of "Zinc sulphate heptahydrate" and Iron sulphate heptahydrate.

The density of heptahydrate zinc sulphate is somewhere 800-100kg/m3 , while for heptahydrate iron sulphate 1890kg/m3.Please find enclosed relevant PDFs..
