You will measure the mass
and volume of the glass beads several times. Thus you will know
their average mass, m, and an estimate its
standard deviation, sm, and their average volume, V, and an estimate of its standard deviation, sV. The
density, d, of the beads is
given by,and an
estimate of the standard deviation in the density, sd, is given by,
Note:
It is meaningless to report a density without units (e.g. g/cm3 ).
The appropriate units MUST always be given.
