Weigh accurately 4.0 g of sodium chloride into a 250cm3 volumetric flask. Using a wash bottle add about 200cm3 of distilled water. Stopper the flask. Shake vigorously for three minutes. Remove the stopper for a second then continue to shake for about another two minutes until all the solid has dissolved. Add more water slowly upto exactly the 250 cm3 mark. 1.Calculate the number of moles of sodium chloride present in: (i) 4.0 g (ii) 250 cm3 solution in the volumetric flask. (iii) one decimeter of solution
