Problem: Bronze is a solid solution of Cu(s) and Sn(s); solutions of metals like this that are solids are called alloys. There is a range of compositions over which the solution is considered a bronze. Bronzes are stronger and harder than either copper or tin alone.Part A. A 160.0-g sample of a certain bronze is 90.0% copper by mass and 10.0% tin. Which metal can be called the solvent, and which the solute?Part B. Based on Part A, calculate the concentration of the solute metal in the alloy in units of molarity, assuming a density of 7.9 g/cm3.

Part A. A 160.0-g sample of a certain bronze is 90.0% copper by mass and 10.0% tin. Which metal can be called the solvent, and which the solute?

copper is the solvent and tin is the solute.


Part B:

molarity (M)=molL

tin → solute

Calcualte moles tin:

mass tin=10%100×160.0 g

mass tin = 16.0 g

molar mass tin = 118.71 g/mol

moles tin=16.0 g×1 mol118.71 g

moles tin = 0.1347 mol


Calculate the volume of solution in L:
