Because I Forgot what you're supposed to do with that ratio , so I figured I'd transform it in ml, since it would make sense to use the same measuring unit to make the darn vodka!

wouldn't I divide it though to get how many moles fit in 60, also I'm limited to 100ml

60/18 = 3.333^. moles of water in this ratio

40/46 = 0.869 moles of ethanol in this ratio

This is all I've got so Far, how do I make this into a 100ml solution

I remember having fun once, it was terrible...

0.869 + 3.333 .... 100%
0.869.... x%
3.333 .... y %
________

x = (100x0.869) / (0.869+3.333) = ...%
y = 100 - x

135.755% ?

redo it, it can't be over 100 ...


Wait. These are moles, you need to get the ratio in ml. Unless you  have any idea how that 100 ml solution is in moles, you should stick to ml... Or at least explain why are you using mols.

sorry. I made a mistake

x% = (100x0.869) / (0.869+3.333)
x% = (86.9)/(4.2)
x% = 20.69%

That's nice, but you have to do the same bit again, only in ml.. (instead of the 0.869 and 3.333, turn those ratios into ml)

ummm... how do I do that

By how I told you to calculate in the first part... If you can find out what 1 mol ethanol is in ml, then we might see The End of this problem...

I think it's 36.294mls in one mole of ethanol (density x molecular weight)
