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 Avogadros 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 Avogadros no.
= 0.25 X 6.022 x 1023
= 1.5055 X 1023 molecules
