Chemistry

Ascorbic acid (vitamin C, C6H8O6) is a water-soluble vitamin. Asolution containing 81.0 g of ascorbic acid dissolved in 220 g ofwater has a density of 1.22 g/mL at 55 ∘C.

Calculate the mass percentage.

Calculate the mole fraction.

Calculate the molality.

Calculate the molarity of ascorbic acid in this solution.

mass of solution = 81+220 = 301g

The mass percentage   = 81*100/301 = 26.9%

no of moles of ascorbic acid   = W/G.M.Wt   = 81/176 = 0.46moles

no of moles of water              = W/G.M.Wt   = 220/18    = 12.22 moles

   molae fraction of ascorbic acid   = no of moles of ascorbic acid/no of moles of ascorbic acid + no of moles of water

                                                      = 0.46/0.46+12.22

                                                        = 0.46/12.68   = 0.0363

molality    = W*1000/gram molar mass * weight of solvent

                   = 81*1000/176*220 = 2.09m

volume of solution = 220/1.22    = 180.32ml

molarity    =   81*1000/176*180.32   = 2.55M
