Answer:
There are 5.69*10²⁴ molecules in 9.45 moles.
Explanation:
The mole is defined as the amount of matter that particles have, that is, atoms and elementary entities.
Avogadro's Number or Avogadro's Constant is called the number of particles that make up a substance (usually atoms or molecules) and that can be found in the amount of one mole of said substance. Its value is 6.023*10²³ particles per mole and represents a quantity without an associated physical dimension. Avogadro's number applies to any substance.
Then the following rule of three can be applied: if 1 mole contains 6.023 * 10²³ molecules, 9.45 moles, how many molecules will it have?
Solving:
amount of molecules= 5.69*10²⁴⁴ molecules
<u><em>There are 5.69*10²⁴ molecules in 9.45 moles.</em></u>
