4.03 x 10²³ atoms
Explanation:
Given parameters:
Number of moles of FeTiO₃ = 0.67moles
Unknown:
Number of atoms = ?
Solution:
From the compound FeTiO₃ ;
1 mole of FeTiO₃ contains 1 mole of Ti atom
0.67 moles of FeTiO₃ will invariably have 0.67 moles of Ti atoms
A mole of any substance is the quantity of substance that contains the Avogadro's number of particles 6.02 x 10²³ particles
The particles are number of atoms, number of protons, neutrons, electrons, molecules e.t.c
1 mole of Ti = 6.02 x 10²³ atoms of Ti
0.67 moles of Ti = 0.67 x 6.02 x 10²³ = 4.03 x 10²³ atoms
