How many moles of aluminum do 5.9×1024 aluminum atoms represent?

9.80

5.9E24/6.02E23 = ?

9.0

To determine the number of moles of aluminum represented by a given number of aluminum atoms, we can use Avogadro's number.

Avogadro's number, which is approximately 6.022 × 10^23, represents the number of atoms or molecules in one mole of a substance. It allows us to convert between the number of particles and the number of moles.

In this case, you have 5.9 × 10^24 aluminum atoms. To find the number of moles, divide this value by Avogadro's number:

Number of moles = Number of atoms / Avogadro's number

Plugging in the values, we have:

Number of moles = 5.9 × 10^24 / 6.022 × 10^23

Dividing these two numbers gives us:

Number of moles ≈ 9.8

So, 5.9 × 10^24 aluminum atoms represent approximately 9.8 moles of aluminum.
