Okay thanks sooooo much! I really really really appreciate your help! It's fine everyone makes mistakes! :)
CHEMISTRY
But Kf= 1.86 degrees C/m not 0.186? So shouldn't it be : dT = 1*1.86*14.46 =26.97 ---> -26.97
CHEMISTRY
What did you get for part b if you disagree with -26?
CHEMISTRY
oohhh so for part d I mixed up molarity and molality my bad...I get it now! So the answer I got in part a is supposed to be used in part d......Thanks! :)
CHEMISTRY
what did you get for part b then?
CHEMISTRY
sorry I typed it wrong....my answer for a) is 14.5 M
CHEMISTRY
for part c: 100g* 1L/920 g= .108695 L M=mols/L 0.87 mols of H2O/.108695 L =8.004 M Is this right? part d: pi= (8.004M) (0.08206) (-26.97+273)= 161.59 atm is this right?
CHEMISTRY
You mix 40.0 g of ethanol (C2H5OH, molecular weight = 46.1 g/mol) and 60.0 g of water (molecular weight = 18.0 g/mol) The resulting solution has a density of 920 g/L. a)Calculate the molarity of ethanol in this solution? Answer : 0.06 kg of H2O This is correct. b) At what temp...
