Układam równanie:
Aby otrzymać procent z danej liczby, mnożymy ją razy 100:
2026*100%=20,26%
mr₁ = V*d = 20cm³*1,02g/cm³ = 20,4g
ms₁ = mr*cp/100% = 20,4g*3%/100% = 0,612g
Roztwór2
mr₂ = V*d = 80cm³*1,18g/cm³ = 94,4g
ms₂ = mr*cp/100% = 94,4g*24%/100% = 22,656g
cp = (ms₁ + ms₂)*100%/(mr₁ + mr₂) = (0,612g + 22,656g)*100%/(20,4g + 94,4g)= 20,25%
