Ohhh i get it...lol

Can't you just use ohm's law? V/I*R

http://www.onlineconversion.com/ This page will let you convert into anything...within reason :P

Thats what i said...lol, but in laymen terms! :P

I know what you mean though...

No..i said mole fraction not w/w

Just do a Process modell using ODE'S Input-output=accumulation. Do it a component balance so only use energy & temp

mcabe & thiele

I am a chemical engineer and my degree was the same as Thearny's one! So, no need to comment..i think he covered it well :P lol

yer , You must include the reboiler...the first step is always the rebolier...see Coulson and Richardson or Geankopolis (mass transfer) .

i bought mine from waterstones for £7.50 ( part of the amazon group), so try amazon on-line.

Yes, charles university in prague! best there is!

i didn't mean water i meant propane...lol

Becuase one is a molarity Molarity = moles / solution ( litres) So for molarity it would be the 0.5 / 10 litres... ( molarity is the moles divided by the amount of solution...so they are different units) Hence moles % molar

i think Then the mole fraction of water is 0.96...so the solution is 96% water and 4%Ethanol...this shoule help you going if you were unsure what the fraction was. Molarity= Moles of Solute / litres of solution Mole fraction (Ethanol) = Moles of Ethanol/ Moles of Ethanol + Water So do...
