Answer:
Check the explanation
Explanation:
Taking a look at the image, I have shown only the energy levels and not the proper curves, because we just need to calculate the energy differences.
Here, S2 denotes a ground state molecule while S2* denotes an excited state molecule
The energy D1, required for dissociation of excited state molecule to 2 ground state atoms is -ve, which means no energy is supplied, rather energy is emitted by this spontaneous dissociation.
Answer is: f<span>ormula for the hydrated compound is CuSO</span>₄·3H₂O.
ω(H₂O) = 25,3% = 0,253.
ω(CuSO₄) = 100% - 25,3%.
ω(CuSO₄) = 74,7% = 0,747.
ω(H₂O) : M(H₂O) = ω(CuSO₄) : M(CuSO₄).
0,253 : M(H₂O) = 0,747 : 159,6 g/mol.
M(H₂O) = (0,253 · 159,6 g/mol) ÷ 0,747.
M(H₂O) = 54 g/mol.
N(H₂O) = 54 g/mol ÷ 18 g/mol.
N(H₂O) = 3.
