Density is very simple… it is simply the mass (similar to weight) of an object divided by its volume…so in this case it would be 158 g/20 ml = 7.9 g/ml

The density should be in units of kg/cubic meter. 20ml is 20×10^-6 m^3. So density is 0.158×10^6/20 kgm^-3.

Milliliters is the same thing as cubic centimeters so just divide 158 by 20.
or 7.9 grams per cubic centimeter
the unknown metal is Iron..btw.
hope this helps!
