How many atoms of iron (fe) are in a sample of 7.38 mol fe? 1.23 x 1023 atoms fe 5.58 x 1023 atoms fe 3.37 x 1024 atoms fe 4.44 x 1024 atoms fe

atoms of Fe

Explanation: According to Avogadro's law, 1 mole of every substance contains Avogadro's number of particles. 1 mole of iron atom contains atoms of Fe.

If 1 mole of Fe contains= atoms of Fe.

then 7.38 moles of Fe contains= atoms of Fe.

The amount of iron (Fe) atoms in a sample of 7.38 moles of iron (Fe) is × atoms.

Given the following data:

To find the amount of iron (Fe) atoms in a sample of 7.38 moles of iron (Fe), we would apply Avogadro's law:

Avogadro's law states that at the same temperature and pressure (STP), equal volumes of all gases have the same number of molecules.

Avogadro's constant = ×

1 mole of iron (Fe) = × atoms.

7.38 moles of iron (Fe) = X atoms.

Cross-multiplying, we have:

× ×

X = × atoms

explanation:

two years ago, when picking flowers in the mountains back of yosemite valley, i found a book. it was blotted and storm-beaten; all of its outer pages were mealy and crumbly. the paper seemed to dissolve like the snow beneath which it had been buried, however; many of the inner pages were well preserved. and although all were more or less stained and torn, whole chapters were easily readable. this is the condition of the great open book of yosemite glaciers today; its granite pages have been torn and blurred by the same storms that wasted the castaway book.
