Question
Gold is alloyed (mixed) with other metals to increase its
hardness in making jewelry. (a) Consider a piece of gold jewelry
that weighs 9.85 g and has a volume of 0.675 cm3. The
jewelry contains only gold and silver, which have densities
of 19.3 and 10.5 g>cm3, respectively. If the total volume of
the jewelry is the sum of the volumes of the gold and silver
that it contains, calculate the percentage of gold (by mass)
in the jewelry
