This problem about Fundamental Electric Science

Given: Each coulomb of charge passed through the electrolyte         bath deposits 661 ?g of copper on the object to be plated. The current         shown in the above figure flows through the bath for 1 hours         and 5 minutes.

Required:  Determine the mass (in grams) of copper deposited                  on the object.

Solution:

M = g  .

This problem about Fundamental Electric Science Each coulomb of charge passed through the electrolyte bath deposits 661 ?g of copper on the object to be plated. The current shown in the above figure flows through the bath for 1 hours and 5 minutes. Required: Determine the mass (in grams) of copper deposited on the object.

Explanation / Answer

we know the formula of charge is:

Q=I*T (A/SEC)...............................1

Q=CHARGE;

I= CURRENT;

T=TIME;

SO

TIME IS 1 HOUR AND 5 MINT=3900 SECONDS

SO CURRENT IS 30 AMPERE.

PUT THE VALUES IN EQUATION 1

Q=3900*30=117000 Coulomb

GIVEN IN QUESTION

661ug/Coulomb

SO MASS = 661*117000 =77.377g ---------------ANSWER
