<span>a. 0.325 g / 63.55 g/mol = 5.11 X 10^-3 moles Cu. SHould form 5.11 X 10^-3 mol Cu2+
b. Should form 5.11 X 10^-3 mol Cu(OH)2
c. 1 g Zn / 65.4 g/mol = 0.0153 mol Zn
Excess Zn = 0.0153 - 0.0051 = 0.0102 moles excess zinc
d. 5.11 X 10^-3 mol Mg X 24.3 g/mol = 0.124 grams Mg</span>

Answer:
14 g
Explanation:
First, we have to calculate the partial pressure of N₂. We know that the air is 80% nitrogen by volume, which, for a gas mixture, means that the mole fraction of N₂ is 0.80.
We can calculate the partial pressure of N₂ (pN₂) using the following expression:
pN₂ = P . x(N₂)
where,
P is the total pressure
x(N₂) is the mole fraction of N₂
pN₂ = 1.1 atm . 0.80 = 0.88 atm
Then, we can calculate the moles of N₂ using the ideal gas equation.
Considering that the molar mass of N₂ is 28.01 g/mol, the mass of N₂ is:
Its a nuclear weapon explosion device that derives its destructive force from nuclear reactions, either fission or a combination of fission and fusion.
