Question

The mass of one screw is 4.1 g. Find the mass of one mole of this screw ? Compare this value with the mass of the earth (6×10^24) and find out which one is heavier and by how much times.​

Answer 1

Answer:

Given that, mass of one steel screw = 4.11 g Mass of earth We know that, 1 mole = 6.022x 1023 atoms/molecules/ions Mass of 1 mole of screws = 6.022x 1023 x 4.11 g = 2.48x 1024 g Mass of 1 mole screw 2.48x 1024 g Ratio of 1 mole of screw and mass of earth = 1:2410 Earth is heavier than screw by 2410 times.
