A student is
presented with two metal samples, A and B,
and must distinguish between
them ( one is ferromagnetic and the
other none magnetic without, the use of a magnet). The student decides to distinguish between them by very carefully measuring their densities ( D=mass/Volume)
; the ferromagnetic metal
has a density of 7.39 g/mL while the non magnetic metal is known to have a density of 7.4215 g/mL. The student measured the mass of a 5.0 mL sample of A to
be 37.0905 g. Calculate the density of
the sample and
determine whether sample A is
ferromagnetic or non magnetic.
