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.
