Each iron atom has a mass of about [tex]$9 \times 10^{-23}$[/tex] grams. Even a small grain of iron has an incredible number of atoms in it—about [tex]$1 \times 10^{18}$[/tex] atoms in one grain.

Which of these is most similar to the number of atoms in a grain of iron?

Answer :

Answer:

A) The number of atoms in a grain of iron is most similar to the number of meters between Earth and Vega.

The options attached to the question are missing, but out of the numbers presented in the options, 10¹⁷ is closest to 10¹⁸.

B) The mass of a grain of iron is approximately (9 × 10⁻⁵) g

Explanation:

The options attached to the question are missing, after searching online, the image of the question was obtained, but it won't be attached to this solution in order not to violate the community guidelines and lead to deletion of answer.

But, out of the numbers presented in the options, 10¹⁷ is closest to 10¹⁸, hence, the number of atoms in a grain of iron is most similar to the number of meters between Earth and Vega.

The second part of the question asks for the approximate mass of a grain of iron.

1 atom of iron has a mass of (9 × 10⁻²³) g

1 grain of iron has about (1 × 10¹⁸) atoms of iron.

So, the mass of a grain of iron = (9 × 10⁻²³) × (1 × 10¹⁸) = (9 × 10⁻⁵) g

Hope this Helps!!!
