Question 1132750: Bachelle wants to know the density of her bracelet, which is a mix of gold and silver. Density is total mass
divided by total volume. The density of gold is 19.3 g/cc and the density of silver is 10.5 g/cc. The jeweler told
her that the volume of silver in the bracelet was 10 cc and the volume of gold was 20 cc. Find the combined
density of her bracelet.

.
Total mass = 19.3*20 + 10.5*10 = 491 gram.


The density = Total_mass%2FTotal_volume = 491%2F%2820%2B10%29 = 491%2F30 = 16.367 gram per centimeter cubic = 16.367 g/cm^3.    ANSWER

Solved.
