Answer :
Answer:
There are approximately 0.232 moles of acetic acid in 1.40 x 10^23 molecules.
Explanation:
We can find the number of moles of acetic acid using Avogadro's constant, which is the number of particles (atoms or molecules) in one mole of a substance. Avogadro's constant is approximately 6.022 x 10^23 molecules/mole.
Here's how to calculate the number of moles:
Define the variables:
Number of acetic acid molecules (given): 1.40 x 10^23
Avogadro's constant: 6.022 x 10^23 molecules/mole (represented by Avogadro's constant symbol)
Formula:
Number of moles (moles) = Number of molecules (molecules) / Avogadro's constant (molecules/mole)
Calculation:
moles = (1.40 x 10^23 molecules) / (6.022 x 10^23 molecules/mole)
Simplifying (round to 3 significant digits):
moles ≈ 0.232 moles
Therefore, there are approximately 0.232 moles of acetic acid in 1.40 x 10^23 molecules.
