Question

If there are 10 moles of copper dissolved in a 40 liter brass solution. What is the molarity?

Answer 1

5000 cm³ (5L) of Cu(NO₃)₂ contain 10 moles
∴ 1000 cm³ of Cu(NO₃)₂ contain x moles

x = (1000 cm³ × 10 moles) ÷ 5000 cm³∴ the concentration of the solution is2 mol/dm³ or 2 mol / L

Answer 2

0.25 M


400 M


0.75 M


4 M
