QUESTION 6 1 pc Complete combustion of 4.5892 a particular compound that contains only carbon, hydrogen and oxygen produces 10.4324 g of CO2 and 4.2705 g of H20. The empirical formula of the compound is given by (indicate "1" if there is only one atom of a given type in the empirical formula.) The molar mass of the compound is found to be 116.16 g/mol in a different experiment. What is the molecular formula of the compound? H

Answer 1

given co2 = 10.4234 g WHO = a - 4.27059 4.2705 -0.957 mola n ne - 4234 0.2321 mole cxtty oz. let the molecular fomento compond be co Cahyoz = 4.5892 g Nexnyoz = 4.5892 mole 12x + y + 162 Now the compution & kN will be CxHyo, +- (2x+| Hd n (to) 4.5892 +y +162 12x 06 2381 0237-1 02371 alt=bo) So.. Xog = no = 0.2307 *= Y or TY=2x] 50 - also on Applying POAC ( Principal of alomic conservation). I on "C"- atom. . 2* 4.5892 0 -2321 12x + y +162 x x 4.5892 0-2321 12 x **+ 162 so form as and ciij X :4:7 = 3:6: empirical formula will be Cc:H:o) C3H60
