Hello,
Can someone give me the simplified chemical formula and molar mass of Clinoptilolite.
I tested the formulas below on webqc but I got no answer
(Na,K,Ca) 2‐3 Al 3 (Al,Si) 2 Si 13 O 36 ∙12H 2 O
(Na,K,Ca)2–3Al3 (Al,Si)2 Si13 O36•12H2O
Formula found on wikipedia
Thanks in advance

Hello,
Thanks for your answer but you give me the molecular formula of
Clinoptilolite ((K0-1Na0-1Ca0-0.5)6(Al6Si30O72).20H2O)
and I am looking for the molecular formula of
Clinoptilolite Na,K,Ca)2–3Al3 (Al,Si)2 Si13 O36•12H2O
Which seems different to me but I could be wrong because I am not a chemist.
Can you confirm that these two molecular formulas are identical
Thanks

It is not possible, because Na,K,Ca 2-3 and Al
3, (Al,Si)
2 can differ in the formula.you have to know the exactly molecule. Na, K, Ca ,Al and Si are exchangable.

The matter is clear and clarified. Na,K,Ca 2-3 and Al
3, (Al,Si)
2 are definitely different in formula. We need to learn more about these substances if we want to prepare anything.

These kinds of notations are typical in geochemistry, mineralogy, and solid-state chemistry, especially when discussing substitution within a mineral lattice.
