Answer :
Final answer:
1.64e24 molecules of propanol (C3H8O) are represented by approximately 2.72 moles.
Explanation:
To calculate the number of moles from the given number of molecules, we need to use Avogadro's number. Avogadro's number is defined as 6.022 x 10^23, and it represents the number of particles (atoms, molecules, ions, etc.) in one mole of a substance.
Given: 1.64e24 molecules
Avogadro's number: 6.022 x 10^23
To find the number of moles, we divide the given number of molecules by Avogadro's number:
Number of moles = Number of molecules / Avogadro's number
Substituting the values:
Number of moles = 1.64e24 molecules / 6.022 x 10^23
Calculating the result:
Number of moles = 2.72 moles
