The Ksp of La(OH) 3 is 2.0x10-21 When activities are considered, what is the concentration of La3+ in a saturated solution with an ionic strength of 0.054 M? .3+ (aq) La(OH)3 (s) = La²) + 3OH(aq KS = 2.0x10-21 sp For La³+ with a charge of +3 and a hydrated radius of 900 pm, the activity coefficient from the extended Debye Hückle equation is 0.233 when the ionic strength is 0.054 M. For OH with a charge of -1 and a hydrated radius of 350 pm, the activity coefficient from the extended Debye Hückle equation is 0.806 when the ionic strength is 0.054 M. Answer using scientific notation with 3 significant digits. For example typing "3.14E-6 M"
