I am stuck on this question and was hoping for someone to help me with the steps necessary for solving it on my own. My instructor never covered this!
A piece of jewelry weighs 9.35g with a volume of 0.654cm3. Assume the metal is an alloy of gold and silver with densities of 19.3 g/cm3 and 10.5 g/cm3 respectively. Assume no volume change when gold ans silver are mixed. Calculate the percent by mass of gold in the jewelry.
