The answer would be 19.3g/cm^3
Explanation: D=m V;D = 38.6g/2cm^3 = 19.3g/cm^3. Due to the chart, the unknown sample is gold. Gold is a soft metal that is malleable and ductile. It has a great density value, which makes it heavy metal.
P= 38.6/2 =19.3g/cm^3
Moles of hydrogen = 5.08 x 10^16
---------------------------
6.02 x 10^23
= 8.43 x 10^-8 moles.
