In a particular electroplating process, the metal being plated has a +4 charge. If 861.8 C of charge pass through the cell, how
Xelga [282]

Answer: 2.2326\times 10^{-3} moles

Explanation:

We are given:

Moles of electron = 1 mole

According to mole concept:

1 mole of an atom contains 6.022\times 10^{23} number of particles.

We know that:

Charge on 1 electron = 1.6\times 10^{-19}C

Charge on 1 mole of electrons = 1.6\times 10^{-19}\times 6.022\times 10^{23}=96500C

The metal being plated has a +4 charge, thus the equation will be:

M^{4+}+4e^-\rightarrow M

4\times 96500C of electricity deposits = 1 mole of metal

Thus 861.8 C of electricity deposits =\frac{1}{4\times 96500}\times 861.8=2.2326\times 10^{-3} moles of metal

Thus 2.2326\times 10^{-3} moles of metal should be plated

Calculate the formula mass of Cuso4​
Mandarinka [93]
Answer: 159.61 g/mol

Copper has a molar mass of 63.546 g/mol

Sulfur has a molar mass of 32.065 g/mol

Oxygen has a molar mass of 16 g/mol, multiply by 4 and it is 16 x 4 = 64 g/mol

63.546 + 32.065 + 64 = 159.61 g/mol
