mr = ms + mrozp = 300g
Cp= ms/mr*100%
Cp=40/300 * 100%
Cp= 13,3%
2.Cp=2% mr = 80g
Cp =ms/mr *100%
ms = mr * Cp/100%
ms=1,6g
Odparowano cala ilosc wody teraz musimy obliczyc mrozp:
mr= ms + mrozp
mrozp = mr - ms = 80g - 1,6g = 78,4g
Czyli od 80 g roztworu odejmujemy 78,4g wody i masa roztworu wynosi 1,6g
3. mr= 300g ms=30g
Cp = ms/mr * 100%
Cp = 10%
