Final answer:
To calculate the charge passed through a galvanic cell, multiply the current by the time in seconds. In this case, a charge of 12 coulombs passed through the cell when it ran for 1.0 minute with a current of 0.20 A.
Step-by-step explanation:
To calculate the amount of charge that passed through a galvanic cell, we can use the relationship between current, charge, and time. The charge transferred (in coulombs) through the cell is the product of the current (in amperes) and the time (in seconds).
The formula to calculate the charge (q) is:
q = I \times t
Where:
- I is the current in amperes (A)
- t is the time in seconds (s)
For a cell running for 1.0 minute with a current of 0.20 A, we first convert the time into seconds:
1.0 minute = 60 seconds
Now we can find the charge:
q = 0.20 A \times 60 s = 12 C
Thus, 12 coulombs of charge passed through the cell in that time.
