Practice Problem
The molarity of copper in a solution of water equals 5.80 × 10⁻⁵ mol/L.
What is the concentration of copper in milligrams per liter (mg/L)? Use the information in the periodic table element box below.
Figure 2. The element box for copper (Cu) from the periodic table.
Formulas
molar mass (atom) = atomic weight (g/mol)
molar mass (molecule) = Σ(atomic weights) (g/mol)
concentration (g/L) = (molarity) × (molar mass)
concentration (mg/L) = concentration (g/L) × 1000 mg/g
