molar to percentage

Recommended Posts

From wikipedia:

"The mole fraction Χ, (also called molar fraction) denotes the number of moles of solute as a proportion of the total number of moles in a solution. For instance: 1 mole of solute dissolved in 9 moles of solvent has a mole fraction of 1/10 or 0.1"

 

I don't understand how this isn't 10%. I know I'm getting wrong, as you guys have told me, but my understanding from this is that the molar of a solution is a percentage the solute takes up of the whole solution. Please tell me what I'm getting wrong!

 

thanks

Please don't take this as in a snarky or mean or putting you down tone. It is not what I mean. But, lboogy, did you read the wili link John posted?

 

Specifically, "Molarity (M) denotes the number of moles of a given substance per liter of solution." Nothing about mole fraction, which is a very different quantity. Molarity has units of moles/liter. Mole fraction would be moles/moles or unitless.
