3. In trying to control Fall armyworms in crops, an Agriculture Extension Officer applied cypermethrin which was prepared by dissolving 200 g of the cypermethrin, C22H19Cl2NO3, in 1000 g of water, HO. Calculate the mole fraction of cypermethrin in the solution. (Atomic masses are: C = 12 amu, H =1 amu, Cl = 35.45 amu, N = 14 amu, O = 16amu). (5 marks)
