This means that you can use the current as a conversion factor to determine that total charge that passed through the solution in 1. Convert the time from hours to second first. Now, a coulomb is equivalent to the charge of 6. This means that the total charge that passes through solution will be equivalent to.
In order to plate the lead out of solution, you must reduce the lead II cations to lead metal. Notice that you need color red 2 moles of electrons in order to produce 1 mole of lead metal. This means that you will have. Finally, to convert this to grams of lead, use the element's molar mass. The answer is rounded to three sig figs. The Standard Model of particle physics and the general theory of relativity describe fundamental particles and the fundamental forces acting between them that control the structure and dynamics of matter.
