Describe the mass fraction of gold

Reference no: EM13549100

The purity of gold alloys is expressed in karats, which is the mass fraction of gold multiplied by 24. Pure gold is 24 kt, whereas 16 kt gold jewelry typically contains 66.666667% gold, 16.666667% silver and 16.666667% copper (by mass). Estimate the density of this 16 kt gold alloy.
