Answer» SOLUTION :Mass of water = 250 g Mass of ethylene GLYCOL = 222 g Total mass = 472 g Density of the solution = 1.07 g/mL Volume of the solution = 472/1.07 = 441 mL = 0.441 L No. of moles of ethylene glycol = `222/62 = 3.58` Molarity = No. of moles / Volume of the solution in litres ` = (3.58)/(0.441) = 8.12 M` |
