A total charge of 97.4 kC passes through an electrolytic cell. Determine the quantity of substance produced in each of the following cases.
(a) the mass (in grams) of silver metal from a silver nitrate solution
?g

(b) the volume (in liters at 273 K and 1.00 atm) of chlorine gas from a brine solution (concentrated aqueous sodium chloride solution)
? L

if sum1 can tell me what equations to use i can probly do them on my own. thx!

96,485 coulombs will produce 1 equivalent weight of material.
You have 97,400 coulomgs which is
97,400/96,485 = ?? coulombs,

1 equivalent weight of Ag is the molar mass/1
1 equivalent weight of chlorine gas is 70.9 g/2. Find grams, convert to moles, and use PV = nRT to find volume.

so for the 1 equivalent weight of Ag i just divide molar mass 107.87 by 1.009 and get 106.8?? is the 1 equivalent weight in material in grams?
Answered by DrBob222
I wouldn't do that.
If 1 C will deposit 107.87 g, then 1.009 C should deposit less? Looks to me that it would deposit more.
Answered by Mark
i thought you were saying to divide by the 1 equivalent?
