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

Answer:
4.2g/cm^3
Explanation:
Density is a measurement of the amount of mass of a substance can fit into a space. In order to find density you can always use the formula mass/volume (often abbreviated as m/v). In this case that would be 42/10 g/cm^3 or 4.2g/cm^3
