Sterling silver is 92.5% silver and 7.5% copper. Its density is 10.25 g/cm3 . A sterling silver pendant is added to a graduated cylinder filled with 50.0 mL of water. The volume rises to 61.3 mL. What is the mass of copper contained in this pendant?
Added by Amanda B.
Step 1
To find the volume of the pendant, subtract the initial volume of water in the graduated cylinder from the final volume after the pendant was added. Volume of pendant = Final volume - Initial volume = 61.3 mL - 50.0 mL = 11.3 mL Show more…

A graduated cylinder was filled with water to the $15.0 \mathrm{~mL}$ mark and weighed on a balance. Its mass was $27.35 \mathrm{~g}$. An object made of silver was placed in the cylinder and completely submerged in the water. The water level rose to $18.3 \mathrm{~mL}$. When reweighed, the cylinder, water, and silver object had a total mass of $62.00 \mathrm{~g}$. Calculate the density of silver in $\mathrm{g} \mathrm{cm}^{-3}$.
