1 mole --------------- 6.02 x 10²³ atoms
( moles iron) -------- 5.0 x 10²⁵ atoms
( moles iron ) = 5.0 x 10²⁵ x 1 / 6.02 x 10²³
moles iron = 5.0 x 10²⁵ / 6.02 x 10²³
= 83.05 moles of iron
hope this helps!
<span>Kinetic energy.
Kinetic energy essentially is possessed by a moving object. The motion of an object, or the release of an elastic band would then give birth to kinetic energy because motion is depicted in the released object.

1. the sun’s rays warm the earth
2. the earth radiates heat which warms the air
3. cool air is warmed and becomes less dense
4. air, which is less dense, rises
5. air rising in the atmosphere expands causing lower air pressure
6. air that expands decreases in temperature
7. air is cooled until water vapor condenses into solid particles in the air
8. tiny cloud droplets collect together to form raindrops large enough to fall towards the earth
