zmieszano 30 g 30-procentowego z 40 g 20-procentowego roztworu wodorotlenku potasu. oblicz sterzenie % otzrymanego roztworu.

Cp=ms/mr x 100% 0,3=ms/30 ms=9g 0,2=ms/40 ms=8g Cp=17/70 x 100% Cp=24,3%

mr1 = 30g cp1 = 30% ms1= 30g*30%/100% ms1= 9g mw1 = 21g mr2 = 40g cp 2 = 20% ms2= 20%*40g/100% ms2 = 8g mw2 = 32g mr3 = 70g ms3 = 17g ms3 = 53g cp3 = ms3*100%/mr3 cp3 = 17g*100%/70 cp3 = 24,28% Wydaje mi sie, ze dobrze :D
