Vypočítajte osmotický tlak a koncentráciu osmoticky účinných častíc v roztoku chloridu hlinitého. Pri teplote 27°C sa v 1 litri roztoku nachádza 3,829 g chloridu hlinitého.
(R= 8,32 J.K-1mol-1)
Osmotický tlak má vyjsť 286,8kPa, to mi vyšlo.
Ale koncentrácia má vyjsť 0,1149mol.dm-3 a mne vyšlo 0,029mol.dm-3, čo je tiež v možnostiach… neviete mi poradiť prosím kde mám chybu? Ďakujem
