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

Since mole ratio of magnesium to hydrochloric acid is 1:2, the answer is 1 mole of HCL.
Answer:
14.2 Liters. That's all I know I just searched it up on wolframalpha.com.
The number next to cobalt (58) represents the atomic mass.
The atomic mass consists of protons and neutrons.
We know that the atomic number = # of protons.
- Look at a periodic table to find Cobalt's atomic number which is 27, meaning there are 27 protons.
-To find the number of neutrons, take 58-27 = 31 neutrons.
Therefore the answer is (1) 27 Protons and 31 Neutrons
