ile wynosi Cp roztworu wodorowęglanupotasu (khco3)w którym na 10 moli h2o przypada 1 mol soli?
MKHCO3=100g/mol
MH2O=18g/mol
ms=100g
mr=10*18g+100=280g
280g - 100g
100g - x
x=100g*100g/280g=35.71g, Cp=35.71%

M H₂O = 18g/mol = 180g/10mol
mr = 280g
ms = 100g
Cp = (ms*100%) / mr
Cp = 100*100/280
Cp = 1000/28 ≈ 35,7%
Proszę bardzo.
