Can someone help me with this Physical Chemistry question that deals with Partial Molar volumes. I missed class and need help! Picture to follow...

Sure, so do you understand that the picture is describing how the shapes of the molecules pack together more tightly when mixed together rather than when completely separate?

anonymous · Answer

yes because the ethanol chain can fit in between the hexagonal structure of the h2o crystal lattice

anonymous · Answer

I feel like its really easy, I'm just missing something. I missed class last week

kainui · Answer

Wait, there's no crystal lattice here, this isn't frozen water.

anonymous · Answer

well, the quasi- lattice from the H-bonds

anonymous · Answer

dude, i need help idk @Kainui

aaronq · Answer

Have you tried using the formula ${V}=\dfrac{M}{\rho}$ to find the necessary molar volume?

anonymous · Answer

those values can be obtained from the graph

anonymous · Answer

ello mate, you need some help?

anonymous · Answer

please! I'm getting frustrated because I'm stumped!

anonymous · Answer

well, too bad im not a chemist..
you know who this is hahahahahaaa

anonymous · Answer

i checked to see if somone asnwered you haha and i called joey hahaha

anonymous · Answer

hahah you bugger
i thought chemistry wise was gunna help me solve the problem:(

anonymous · Answer

sorry bubbbaaa, ask @aaronq , help my man!!

aaronq · Answer

alternatively, you could find the mole fraction of when using 50 g of each. I don't think you can just look at the graph and find the values because the molar mass of each is involved (and they're not the same).
