a solution of glcose in water is leveled as 10% by w/w.what would be the molarity and mole fraction of each component in solution.if the density of solution is 1.2gm/ml. then what is the molarity of solution??

Solution

10% glucose in water w/w means 10g of glucose is present in 100g of solution (90g of water is present)
Moles of glucose = mass/molar mass = 10/180 = 0.056mol
Moles of water = 90/18= 5mol
Total moles = 5+ 0.056 = 5.056mol
Mole fraction of glucose = moles glucose/total moles = 0.056/5.056= 0.01
Mole fraction of water= moles water/total moles = 5/5.056 = 0.99

Molarity = moles of solute (glucose)/volume of solution in L

Volume = mass/density = 100 /1.2 = 83.33ml = 0.083 L
Molarity = 0.056/0.083=0.67M
