Cp=ms/mr * 100%
Pierwszy roztwor:
0,1=ms/125
ms=12,5g kwasu
Drugi roztwór:
0,06=ms/175
ms=10,5g kwasu
Po zmieszaniu:
Cp=(10,5+12,5)/(125+175)*100%
Cp=7,7%
125g 10%...............x - 6
................x%
175g 6%................10 - x
125/175 = x-6/10-x
125(10-x) = 175(x-6)
1250 - 125x = 175x - 1050
300x = 2300
x = 7,67%
