Question

How many atoms are in 2.50 moles of iron

Answer 1

To find the number of atoms in 2.50 moles of iron, multiply the number of moles by Avogadro's number (6.022 \u00d7 1023 atoms/mole), resulting in 1.505 \u00d7 1024 atoms.

Step-by-step explanation:

To determine how many atoms are in 2.50 moles of iron, we can use Avogadro's number, which is the number of atoms per mole. Avogadro's number is approximately 6.022 \u00d7 1023 atoms per mole.

Step 1: Find the number of atoms by multiplying the number of moles by Avogadro's number:
Number of atoms = Number of moles \u00d7 Avogadro's number

2.50 moles \u00d7 6.022 \u00d7 1023 atoms/mole = 1.505 \u00d7 1024 atoms

So, there are 1.505 \u00d7 1024 atoms in 2.50 moles of iron.

Answer 2

There are 1.505535375e+24 atoms in 2.50 moles of iron.
