Explain why sportsmen use shoes with spikes.

Dear Student,

Please find below the solution to the asked query:

Atomic mass of silicon is 28 g

So, 28 g of silicon has 6.023 $\times$ 10²³  atoms

In 35 g of silicon, number of atoms of silicon = (6.023 $\times$10²³ /28)  $\times$ 35 = 7.52 $\times$10²³ atoms

Hope this information will clear your doubts about the topic.

Regards
