Mass of Copper metal dissolved = 0.1090 g
Moles of Copper dissolved = [tex] 0.1090 g * \frac{1 mol}{63.55 g} = 0.00172 mol Cu [/tex]
Total volume of the solution = 203.1 mL [tex] * \frac{1 L}{1000 mL} = 0.2031 L [/tex]
Calculating the molarity of copper ions in the solution:
Molarity of a solution = [tex] \frac{Moles of solute}{Volume of solution (L)} [/tex]
= [tex] \frac{0.00172 mol Cu^{2+}}{0.2031 L} [/tex]
=0.00845 mol/L
Therefore the molarity of copper ions is 0.00845 mol/L
