Odpowiedź:
Po dodaniu cukru stężenie wynosi 30%
Wyjaśnienie:
mr1 = 200g
Cp1 = 20%
ms1 = ?
Cp = [tex]\frac{ms}{mr}[/tex] * 100% | * mr
Cp * mr = ms * 100% |:100%
[tex]\frac{Cp*mr}{100}[/tex] = ms
ms = (20% * 200g)/100%
ms =40 g
mr2 = 200g + 30g = 230 g
ms = 40g + 30g = 70g
Cp = ?
Cp = [tex]\frac{ms}{mr}[/tex] * 100%
Cp = [tex]\frac{70g}{230g}[/tex] * 100%
Cp = 30%
