1.2 x 1024 atoms of iron would be _____________ moles of iron

To convert atoms to moles, you can use Avogadro's number, which is 6.022 x 10^23 atoms/mole.

Step 1: Identify the given number of atoms, which is 1.2 x 10^24 atoms of iron.

Step 2: Use Avogadro's number to convert atoms to moles.

The formula to convert atoms to moles is:

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

Step 3: Substitute the given number of atoms and Avogadro's number into the formula:

Number of moles = 1.2 x 10^24 atoms / 6.022 x 10^23 atoms/mole

Step 4: Perform the division to find the number of moles.

The result is approximately 1.99 moles of iron.
