Answer:
9.14moles
Explanation:
Given parameters:
Number of atoms of butane = 5.5 x 10²⁴atoms
Unknown:
Number of moles = ?
Solution:
To solve this problem, we must understand that a mole of any substance contains the Avogadro's number of particles.
6.02 x 10²³ atoms makes up 1 mole of an atom
5.5 x 10²⁴ atoms will contain = = 9.14moles
Answer : The energy involved in condensation is, 339 kJ
