A solution of ethanol in water boils at 101.5 degrees C. what it tne molarity? Can you show me the setup i would use??
I did the first time you posted this problem.
delta T = i*Kb*m
delta T = 101.5 - 100 = 1.5
i = 1
kb = 0.51
m = ??
m equals molarity
i thought it equals moles!!!!!
m = molality.
the abbrev for moles is mols.
then for those other problems we converted molarity into grams??
and the final answer for the ethanol one is 2.94
2.94 m = 2.94 molal is what I obtained. Yes, for the other problems we converted molality into grams from molality = mols solute/kg solvent.
WHAT ARE THE THREE ANSWERS YOU GOT!!
C6H1206= 84.4
CACL2= 13.92
