Author: Subject: DRY HYDROGEN CHLORIDE GAS - …

The "Molar mass" of calcium chloride is 110.98 g/mol and for water (H2O) it''s 18.01528 (33) g/mol. So this means that 110.98 grams of calcium chloride (anhydrous) can absorb 18 grams of water. I forget how HCL works and there is no point in me trying because I can''t find the info that I''m looking for.
