What will be the weight of CO having the same number of O-atoms as present in 22 g of CO2?

Number of O-atoms in 22 gCO2=2 Molar mass of CO2=44 g  44 g=1 mol                                       22 g= 0.5 mol1 mole of CO2 contains =2×6.023×1023O-atoms 0.5 mole of CO2=6.023×1023O-atom  Number of O-atoms in CO=6.023×1023 molecules of CO                                            = l mole of CO1 mole of CO=6.023×1023O-atoms Molar mass of CO = 12 + 16 = 28 g
