To get the density of the material, the formula would be: mass divided by volume which is denoted by d = m/v
So for this problem, the mass is 241.25 g and the volume is 12.5 cm^3
so plugging in the data, we have: d = 241.25 g / 12.5 cm^3 = 19.3 g/cm^3
The answer is Tungsten, you could see it in the table, in the attached file.
