False.
The atoms or molecules do have motion, but it is barely detectable.

Answer: 7.56 moles
Explanation:
C3H8 is the chemical formula for propane, the third member of the alkane family.
Recall that based on Avogadro's number, 1 mole of any substance has 6.02 x 10^23 atoms
So 1 mole of C3H8 = 6.02 x 10^23 atoms
Z moles of C3H8 = 4.55 x 10^24 atoms
To get the value of Z, we cross multiply:
1 x 4.55 x 10^24 atoms = Z moles x (6.02 x 10^23 atoms)
4.55 x 10^24 atoms = Z moles x (6.02 x 10^23 atoms)
To get the value of Z divide both sides by 6.02 x 10^23 atoms
Z moles =4.55 x 10^24 atoms ➗ 6.02 x 10*23 atoms
Hence, Z = 7.56 moles
Thus, the number of propane, C3H8 is 7.56 moles
