How can we enter the formula of compounds like FeO2.33 or A0.2B0.8Se etc.?

code4Siddharth commented 3 years ago

Yes, for example, if I want to calculate the molecular mass of Sr_0.5La_0.5TiO_3 it gives an error
FormulaError: count is zero Sr0(La0)5(TiO3)5 ......^

Sorry, molmass formulas can not contain fractional numbers.
