How many atoms are in 13.2 grams of iron?

Answer 1

The conversion string.

13.2g Fe ( 1mol Fe/55.85g Fe ) ( 6.022 X 10^23/ 1mol Fe )

= 1.42 X 10^23 atoms

Answer 2

To calculate the number of atoms in 13.2 grams of iron, you first need to determine the molar mass of iron, which is approximately 55.85 g/mol. Then, you can use Avogadro's number (6.022 x 10^23 atoms/mol) to convert grams to atoms. Therefore, there are about 4.49 x 10^22 atoms in 13.2 grams of iron.
