Quandaries & Queries

Question from Helen, a student:

What would the volume (in mL) of a 3 ounce piece of gold be?
16oz= 1lb
1lb= 454oz.
first i converted 3oz to lbs and then to grams to get the mass. i got 85.125 g.
now i don't know how to get the density to get to the volume.

Helen, you would have to look up the density in a reference book or a web site.

All of the reference sites I've looked at, including this one, gives the
density of gold at 19.3 g / mL.

Cheers,
