Taking into account the definition of Avogadro's Number, 7.80×10²² molecules of HCl are contained in 0.1295 moles of HCl.
<h3>
Avogadro's Number</h3>
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. Avogadro's number applies to any substance.
<h3>This case</h3>
Then you can apply the following rule of three: if 6.023×10²³ molecules are contained in 1 mole of HCl, then 7.80×10²² molecules are contained in how many moles of HCl?
amount of moles of HCl= (7.80×10²² molecules × 1 mole)÷ 6.023×10²³ molecules
<u><em>amount of moles of HCl= 0.1295 moles</em></u>
Finally, 7.80×10²² molecules of HCl are contained in 0.1295 moles of HCl.
