Oblicz stężenie procentowe roztworu powstałego w wyniku rozpuszczenia 45g substancji w 405g wody.
Cp = ms*100% / mr
Cp = 45g*100% / (405g + 45g)
Cp = 45*100% / 450g
Cp = 10%
D;
ms = 45g
mw = 405g
mr = ms + mw
mr = 405g + 45g = 450g
sz;
Cp= ?
Cp = ms/mr * 100%
Cp = 45g/450g *100%
Cp = 0,1 = 10%
odp; stezenie procentowe wynosi 10%
