60 g - masa soli
x + 60 - masa roztworu
8% - stęzenie
60 / ( x+60)× 100% = 8%
60 / ( x+60) = 0,08 / × ( x+60)
60 = 0,08x + 4,8
55,2 = 0,08x /: 0,08
690 = x
Należy dodać 690 gram wody.
Masa roztworu 690 + 60 = 750g
Cp = 8% mr = ?
ms = 60g
mr = ms * 100% / Cp
mr = 60g * 100% / 8%
mr = 750g
Z 60 g soli uzyskamy 750g roztowru 8%
