Question

20. The density of lead is 11.3 g/cm3. A cubed of metal had a measurement of 2.25 cm on
each side and had a mass of 129.5g. Is the metal lead?

Answer 1

Answer:  The metal is Lead

Explanation:

For the metal to be lead, it must have same density (~ 11.3 g/cm³).

Density = mass ÷ volume

             =  ( 129.5 g ÷ (2.25 cm)³)

             =  11.37 g/cm³

⇒  the metal is Lead.
