Question

How many moles are there in 8.46 x 1024 molecules of sodium fluoride?

Answer 1

14.05 moles

Step-by-step explanation:

Answer 2

14.05moles

Step-by-step explanation:

Given parameters:

Number of atoms of NaF = 8.46 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

8.46 x 10²⁴ atoms will contain =
`(8.46 x 10^(24) )/(6.02 x 10^(23) )` = 14.05moles
