Chapter 17: Q2P (page 427)

How many hours are required for 0.100 mol of electrons to flow through a circuit if the current is 1.00 A?

Short Answer

Expert verified

Total hours requires for electrons to flow through a circuit is t = 2.68h

Step by step solution

01

Step1: Determination of electrons:

  • Electrons move through a wire from the negative end to the positive end.
  • The resistor uses the energy of the electrons around the wire and slows down the flow of electrons.
02

 Calculation of electrons:

Given data,

n(e-)=0.1moll=1At=?

The charge of electrons is calculated

n(e-)=qn.F

The is 1, so the q is,

q=n(e-).Fq=0.1mol.96485C/molq=9648.5C

03

Step 3: Ascertaining the flow of current in hours:

Now we can calculate using the formula,

q=l.t

Where is,

t=ql=9648.5C1At=9648.5s=2.68h
