M H2S = 34g\mol
100 dm3 ----- xg
22,4 dm3 ---- 34g
x = około 152g
V wody = 1dm3 = 1000cm3
d wody = 1g\cm3
d = m\V
m = d*V
m wody = 1g\cm3*1000cm3
m wody = 1000g
mr = ms + m wody
mr = 152g + 1000g
mr = 1152g
Cp = ms\mr*100%
Cp = 152\1152*100%
Cp = około 13,2%
Odp: Stężenie procentowe roztworu wynosi około 13,2%. ;)
