24518 is the answer to your queston
Answer: 281 hours
Explanation:-
1 electron carry charge=
1 mole of electrons contain=
electrons
Thus 1 mole of electrons carry charge=

of electricity deposits 1 mole or 63.5 g of copper
0.0635 kg of copper is deposited by 193000 Coloumb
11.5 kg of copper is deposited by=
Coloumb

where Q= quantity of electricity in coloumbs = 34952756 C
I = current in amperes = 34.5 A
t= time in seconds = ?


Thus it will take 281 hours to plate 11.5 kg of copper onto the cathode if the current passed through the cell is held constant at 34.5 A.
Answer:
The answers are as given in the attachment
Explanation:
The application of the de brogile equation was used and appropriate substitution were made as shown in the attachment
Nuetrons=neutral
protons =positive
electrons=negative
The mass of 3.58 mol of CuCl₂ . 2H₂O is 610.31 grams.
<h3>What is mass?</h3>
Mass is the quantity of matter in a physical body. The product of the molar mass of the compound and the moles of the substance are defined as mass.
The formula is
Mass = molar mass x moles
The molar mass of CuCl₂ . 2H₂O = 170.48 g/mol
To find the molar mass of the compound, add all the atoms of one molecule.
The moles of CuCl₂ . 2H₂O is given that is 3.58 mol
Substituting the value in the formula
3.58 mol x 170.48 g/mol = 610.31 gram
Thus, the mass of 3.58 mol of CuCl₂ . 2H₂O is 610.31 grams.
