How many moles of butane do we have if we have 5.50 x 1024 molecules
of butane (CH) ?

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
