In the first place we are going to assume that the form of the Titanium is a perfect square, so that the volume is calculated as:V = s^3 V = (2.84)^3V = 22.91 in^3, Then calculate the mass:m = (4.50 g/cm^3)*22.91 in^3*(2.54 cm/1in)^3m = 1,689.15 g of Calculation for the number of atoms by dividing molar mass (47.87 g/mol) and multiplying with Avogadros:number of atoms = [(1,689.15 g) / (47.87 g/mol)] * (6.022 x 10^23 atoms/mol)atoms = 2.125 x 10^25 atoms
