estimated elemental composition and molecular weight 
Minerals with the same name may vary widely in appearance and composition, and very few are >99% (reagent grade) pure.

Gram formula weight (molecular mass) = 160.60


Minerals may vary in elemental composition and impurity levels. The formula given is an approximation.
