Mass=18.2g

Volume=2.56cm^3

=> Density =

=  >  \frac{mass}{volume}

=> Density=

\frac{18.2}{2.56}

=> Density=

7.1g/cm {}^{3}

First calculate density of the the metal (should equal to density of iron)

  • Mass=18.2g
  • Volume=2.56cm^3

\\ \bull\tt\longmapsto Density=\dfrac{Mass}{Volume}

\\ \bull\tt\longmapsto Density=\dfrac{18.2}{2.56}

\\ \bull\tt\longmapsto Density=7.1g/cm^3

Metal is not iron
