Question: how many molecules are in 8.0 moles of carbon dioxide (co2)?
Answer: So, 44 g of CO2 will contain 6.023x 10 ^ 23 molecules. Since in 1 mole of CO2 6.022*10^23 molecule exist whose mass is 44g hence in 8.8g of CO2 0.2 mole of molecules i.e 12.044*10^22 molecules will be present. There are 1.2046×10^23 number of molecules of CO2 in 8.80 g of CO2.
