One mole of screws weigh = 2.475 ×1024g            = 2.475×1021 kg 

Mass of the Earth / Mass of 1 mole of screws = 5.98 ×1024 kg / 2.475× 1021 kg

                                                                        = 2.4 ×10    

Mass of earth is 2.4×103 times the mass of screws 

The earth is 2400 times heavier than one mole of screws
