<u>Answer:</u> The amount of time needed for 1 mole of electrons to pass through the lamp is 12.33 hrs.
<u>Explanation:</u>
We are given:
Moles of electron = 1 mole
According to mole concept:
1 mole of an atom contains
number of particles.
We know that:
Charge on 1 electron = 
Charge on 1 mole of electrons = 
To calculate the time required, we use the equation:

where,
I = current passed = 2.17 A
q = total charge = 
t = time required = ?
Putting values in above equation, we get:

Converting this into hours, we use the conversion factor:
1 hr = 3600 seconds
So, 
Hence, the amount of time needed for 1 mole of electrons to pass through the lamp is 12.33 hrs.
Answer:
y = -3x + 1
Explanation:
Isolate the variable, y. Note the equal sign, what you do to one side, you do to the other. Subtract 3x from both sides of the equation:
3x + y = 1
3x (-3x) + y = 1 (-3x)
y = -3x + 1
y = -3x + 1 is your answer.
