Question

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

Answer 1

9.14moles

Step-by-step 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 =
`(5.5 x 10^(24) )/(6.02 x 10^(23) )` = 9.14moles
