The mole fraction is the number of moles of one substance divided by the total number of moles.
Density of water = 1g/ml
So, mass of water = 200g
Molar mass of H2O = 18g/mol
So, moles of water = 200/18 = 11.111
Total moles = 11.111 + 0.100 = 11.211
So, mole fraction of C6H12O6 = 0.1/11.211 = 0.009
Mole fraction of water = 11.111/11.211 = 0.991

Take the molecule weight of this molecule.
6 x carbon weight + 12 x hydrogen weight + 6 x oxygen weight
= A
1 mol = A grams
0.100 mol = 0.100 x A grams
The definition of mole fraction is calculated for each atom, i believe. I have no table of the periodic system by hand, so i can not help you more.

This mixture makes the mole fraction of a Kool Aid.... Thats really quite stupendous. Way to go. Keep up good work

I will be waiting for the answers too.
I need the concentration too.
