Which aqueous solution freezes the lowest temperature?
a)0.30 m C2H5OH B) 025 M KNO3
C) 0.20 M CaBr2 d) 0.10 m FeCl3
when I calculate the molarity for all of them, it turns out the answer is B but I'm nit sure.
please help

Best ResponseYou've already chosen the best response.2okay, so next time copy the question correctly. capital M is molarity and lowercase m is molality. they're different. Use the formula \(\Delta T=i*m*Kb\) Kb is constant, so focus on the value for i, the van't hoff constant, and the molality. I can tell you it's not b)
