Answer: Measure 114 mL of the 1.75 M solution, and dilute it to 2.00 L.
Explanation:
The number of moles in the solution will remain same on dilution and thus according to Molarity Equation:
= molarity of first solution
= Volume of first solution
= molarity of second solution
= Volume of second solution
Thus 114 ml of 1.75 M solution is taken and the volume is diluted to 2.0 L to make 0.100 M solution.
It take 0.54 hours to deposit 6.36g of copper
<h3>Further explanation</h3>Faraday's Law I
"The mass of the substance formed at each electrode is proportional to the electric current flowing in the electrolysis
W = e.i.t / 96500
e = equivalent = Ar / valence
i = current, A
t = time, s
W=6.36 g
e = 63.5 : 2 =31.75
i = 10 A

Hello!
In this case, when looking over the chemical formula of a compound formed when two elements interact, we need to realize about their location in the periodic table; thus, since lithium is a metal and oxygen a nonmetal, we infer lithium turns out the cation and oxygen the anion. Moreover, as the oxidation state of lithium is 1+ and that of oxygen is 2-, we can set up the chemical formula as follows:
