A can of pet food has the following internal dimensions: \(102 \mathrm{~mm}\) height and \(73 \mathrm{~mm}\) diameter (each \(\pm 1 \mathrm{~mm}\) at odds of 20 to 1). The label lists the mass of the contents as \(397 \mathrm{~g}\). Evaluate the magnitude and estimated uncertainty of the density of the pet food if the mass value is accurate to \(\pm 1 \mathrm{~g}\) at the same odds.
