Expert Answer:

Mass of oxygen = 8 g

Hence, Moles of oxygen = 8/16 = 0.5
Now, for two moles of oxygen, CO2 = 1 mole
Similarly, for one mole of oxygen, CO2 = 0.5 mole
For 0

Mass of oxygen = 8 g

Hence, Moles of oxygen = 8/16 = 0.5
Now, for two moles of oxygen, CO2 = 1 mole
Similarly, for one mole of oxygen, CO2 = 0.5 mole
For 0.5 moles of oxygen, CO2 = 0.5 × 0.5 = 0.25 moles

Hence, the number of molecules will be = No. of moles X Avogadro’s no.

                                                                         = 0.25 X 6.022 x 1023

                                                                         = 1.5055 X 1023 molecules      

.5 moles of oxygen, CO2 = 0.5 × 0.5 = 0.25 moles

Hence, the number of molecules will be = No. of moles X Avogadro’s no.

                                                                         = 0.25 X 6.022 x 1023

                                                                         = 1.5055 X 1023 molecules
