This is a subjective question, hence you have to write your answer in the Text-Field given below. (a) Sodium Chloride weighing 200kg is mixed with 600kg of potassium chloride. Calculate the composition of the mixture in (i) weight % and (ii) mole %. [Given: Molecular weight of NaCl=58.5, Molecular weight of KCl=74.5 ] [3] (b) Calculate the average molecular weight of the gas sample that has the composition in terms of the mole % as: CH4=66%,CO2=30mol2, NH3=4%. [Given : Molecular weight of CH4=16, Molecular weight of CO2=44, Molecular weight of NH3=17] [2]
