Molarity of a given solution is the number of moles of a solute dissolved in 1 liter of the solvent
Concentration of glucose solution = 0.1 M
This implies that there are 0.1 moles of glucose in 1 liter of water.
Now,
1 mole of glucose contains 6.023 * 10^23 molecules of glucose
Therefore, 0.1 mole of glucose would correspond to :
0.1 * 6.023 * 10^23/1 = 6.023 * 10^22 glucose molecules.
