1.) The density of iron is 7.9 g/cm3
. In an experiment I
found the mass of my sample to be 118 grams and the
volume to be 14 cm3
. What the density based on my
experiment and what is the relative error of my answer?
2.) The density of is 8.9g/cm3
. In an experiment I found the
mass of my sample to be 850 grams and the volume to be
100 cm3
. What the density based on my experiment and
what is the relative error of my answer?
