We know that 1 mole of Cadmium (Cd contains) 6.023*1023 atoms, which is Avogadro's number.

So in 14 Grams of Cadmium, the number of atoms present is,

=>14×number atoms present in one cadmium atom

=> $14\times 6.023\times10^{23}$

=> $8.4322\times10^{24} atoms$

Answer:

232 g CO2

2 C8H18 + 25 O2 --> 16 CO2 + 18 H2O

75.3 g C8H18 (1mol / 114.26g) (16 mol CO2/2 mol C8H18) (44.01 g/1 mol) = 232 g
