To calculate the quantity of electricity passed (in coulombs), we can use the formula:


Quantity of electricity( in Columbs) = Current (in amperes) × Time (in seconds)
First, let's convert the time from hours and minutes to seconds:

1 hour 20 minutes = 1 hour + 20 minutes = 1 × 3600 seconds + 20 × 60 seconds = 3600 seconds + 1200 seconds = 4800 seconds

Now, let's use the formula:
Quantity of electricity = 0.4A × 4800s= 1920C


So, the quantity of electricity passed when 0.4A flows for 1 hour 20 minutes through an electrolytic cell is 1920 coulombs.

Therefore, the correct answer is (c) 1920c.
