The density of silicon is 2.33 g/cm3. What volume of silicon (in cm3 to 3 sig figs) would contain 7.13 X 1026 atoms of silicon?

please note that we have

(7.13*10^26)/(6.022*10^23) = 1.18*10^3  mol of atoms of silicon, then we have:

1.18*10^3* 55.85=65.9 * 10^3 grams of silicon, and then a volume of:

65.9 *10^3/2.33=28.28 *10^3 cm^3 or 2.828*10^4 cm^3
