a)i) volume of oxygen reacted : 10 * 6.5 =65
so the volume unreacted will be : 100(total volume of o2) - 65 =35 cm3
volume of 6.5 moles of O2 was 65 cm3
so volume of 4 moles of CO2 will be 40 cm3 (we cross-multiply)
a)ii) incomplete combustion means not enogh oxygen so alkane will therefore produce carbonmonoxide (which is dangerous)
hope u get it !!

And remember the 2 rules about Moles , Mole = Concentration × Volume and Mole = Mass / Relative Atomic or Molecular Mass
