Which one of the following aqueous solutions has a freezing point of –2.60°C? (Kf for water is 1.86°C/m)
A. 1.30 m Na2CO3(aq)
B. 0.47 m NaBr(aq)
C. 0.20 m K2SO4(aq)
D. 0.35 m AlCl3(aq)
E. 0.24 m CH3OH (aq)
How do I solve this problem using change in temperature= H freezing times molality?
Can you please show me the work?
