Kobotan [32]

In order of increasing percent water content:CoCl₂.6H₂O, Ba(OH)₂.8H₂O, MgSO₄.7H₂O

<h3>Further explanation</h3>

$\tt \%element=\dfrac{Ar~element}{MW~compound}\times 100\%$

CoCl₂.6H₂O.MW=237.90 g/mol

6H₂O MW = 6.18=108 g/mol

$\tt \%H_2O=\dfrac{108}{237.9}\times 100\%=45.4\%$

MgSO₄.7H₂O.MW=246.48 g/mol

MW 7H₂O = 7.18=126 g/mol

$\tt \%H_2O=\dfrac{126}{246.48}\times 100\%=51.1\%$

Ba(OH)₂.8H₂O MW=315.48 g/mol

MW 8H₂O = 8.18=144 g/mol

$\tt \%H_2O=\dfrac{144}{315.48}\times 100\%=45.6\%$
