Question

Am nevoie de ajutor,

Answer 1

8474 mg = 8,474g CO2

44g CO2 .................... 12g C

8,474g CO2 ................. x = 2,311g C

2,6-2,311 = 0,289 g H

notam hidrocarbura CaHb

2,6 g hidrocarbura ........... 2,311g C ................ 0,289g H

54 g hidrocarbura ................ 12a g C ............... b g H

=> a = 4 ; b = 6

=> hidrocarbura = C4H6
