    I'm assuming that you're talking of a piece of the same volume. If
    that's the case then we can look at the relative densities as though
    they are masses. Therefore, if you divide the relative density of
    silver (10.5 g/cm3) by that of copper (9.0 g/cm3) you get a factor
    of 1.17, therefore, if you have a piece made in copper, weigh it,
    multiply it by 1.17 and that will tell you roughly what it will
    weigh in silver.
