Gravity when the mantle cools it becomes heavier and therfore sinks
Answer:
3.02x10²⁴
Explanation:
To solve this problem we need to use <em>Avogadro's number</em>: It is the number of units (usually atoms or molecules, in this case it's trucks) contained in one mol: 6.023x10²³.
We <u>multiply the given number of moles times Avogadro's number</u>:
5 * 6.023x10²³ = 3.02x10²⁴
So five moles of trucks would be 3.02x10²⁴ trucks.
The periods inside the Periodic Table is B. a horizontal row, and is numbered 1 through 7
