Question

The mass of one steel screw is 4.11g.Find the mass of one mole of these steel screws.

Answer 1

Mass of 1 mole of steel screw will be = 4.11g x 6.023 x1023 = 24.74 x 1023 = 2.47 x 1024 g = 2.47 x 1021 Kg
So of course earth is heavier than one mole of steel screw.
To find how many time let us divide it: 5.98 x 1024 / 2.47 x 1021 = 2.42 x 103 times
hope it's clear to you...
