Problem

A student designs an ammeter (a device that measures electrical current) that is based on the electrolysis of water into hydrogen and oxygen gases. When electrical current of unknown magnitude is run through the device for 2.10 min , 12.1 mL of water-saturated H2 (g) is collected. The temperature of the system is 25.5 oC, and the atmospheric pressure is 761 torr .

What is the magnitude of the current in amperes?
