The first thing we need to do is convert 250 ml of water into moles of water. Remember that 1 ml of water = 1 grams of water, so we have 250 grams of water. 250 grams/18 grams (the molar mass for water) gives us 13.9 moles of solvent. Now remember, a mole fraction is moles solute divided by total moles, so we must add the sugar moles and water ...
