During lab, a student weighs out 1.403 g of pure CuO. The solids were then dissolved in 15 mL of 6.0 M HCl, and 50 mL of water was added. Finally, the student added 0.650 g of Mg metal to the reaction beaker. Based on the mass of CuO added, how many moles of Cu2+ ions were present? Give your answer to 3 significant figures. mol Cu²+ ions Based on the mass of Mg metal added, how many moles of Mg were present? Give your answer to 3 significant figures. mol Mg metal If the copper (II) ions and magnesium react as shown below, was enough mg metal added? Type yes or no. Cu²+ (aq) + Mg(s) → Cu (s) + Mg²+ (aq)

Question
Transcribed Image Text:During lab, a student weighs out 1.403 g of pure CuO. The solids were then dissolved in 15 mL of
6.0 M HCl, and 50 mL of water was added. Finally, the student added 0.650 g of Mg metal to the
reaction beaker.
Based on the mass of CuO added, how many moles of Cu2+ ions were present? Give your answer
to 3 significant figures.
mol Cu²+ ions
Based on the mass of Mg metal added, how many moles of Mg were present? Give your answer to
3 significant figures.
mol Mg metal
If the copper (II) ions and magnesium react as shown below, was enough mg metal added? Type yes
or no.
Cu²+ (aq) + Mg(s) → Cu (s) + Mg²+ (aq)
