1.Do 60g roztworu soli o stężeniu 12% dodano 20g soli. Oblicz Cp tego roztworu. 2.Do 90g 12% roztworu dodano 30g wody. Oblicz Cp tego roztworu.

Zadanie 1 ms = 60g*12%+20g = 60g*0,12+20g = 7,2g+20g = 27,2g mr = 60g+20g = 80g Cp = 27,2g/80g*100% = 0,34*100% = 34%   Zadanie 2 ms = 90g*12% = 90g*0,12 = 10,8g mr = 90g+30g = 120g Cp = 10,8g/120g*100% = 0,09*100% = 9%
