Answer:

0.42mole

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 [tex]\frac{2.5 x 10^{23} }{6.02 x 10^{23} }[/tex]   = 0.42mole
