Question

7. I have 2.50 x 1023 atoms of titanium. How many moles of titanium dol
have?

Answer 1

0.42mole

Step-by-step explanation:

Given parameters:

Number of atoms of titanium = 2.5 x 10²³atoms

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

2.5 x 10²³ atoms will contain
`(2.5 x 10^(23) )/(6.02 x 10^(23) )` = 0.42mole
