Question 90628
First you must find the total displacement of the water in the graduated cylinder once the gold has been placed into it.

The initial water volume was 140 ml, and after the gold was placed into the cylinder it became 200 ml.
Therefore, the volume displacement (or volume of the gold) is:
{{{V=200ml-140ml}}}
{{{200ml-140ml=60ml}}}


Now use the formula,
{{{density=mass/volume}}} to determine the gold's density
so, {{{density=1158g/60ml}}}
which equals {{{1158g/60ml=19.3}}}{{{g/ml}}}
