Oblicz rozpuszczalność azotanu (V) potasu jeżeli otrzymano 8,64g tej soli po odparowaniu do sucha 50g roztworu.
8.64 -50g = 8.14 g azotanu
Odp : Rozpuszczalnośc azotanu(V) wynosi 8.14 g :)
mr = 50g
mH2O = mr - ms
mH2O = 50g - 8,64g = 41,36g
8,64g soli x
----------------- = -----------
41,36g wody 100g wody
x = 20,89g
