Answer to Question #62533 in General Chemistry for Jocelin
Question #62533
Boiling points please help me: highest to lowest boiling points 0.24 mKNO3 0.15 mNa2CO3 0.26 mNaCH3COO 0.54 mUrea(non electrolyte)?
Expert's answer
ΔE=iKm
i for KNO3=2
Na2CO3 =3
CH3COONa = 2
Urea = 1
im(KNO3)=0,48
im(Na2CO3)=0,45
im(CH3COONa)=0,52
im(Urea)=0,54
Highest boilg point has urea>CH3COONa>KNO3>Na2CO3 – lowest boiling point
i for KNO3=2
