A student designs an ammeter (a device that measures electricalcurrent) that is based on the electrolysis of water into hydrogenand oxygen gases. When electrical current of unknown magnitude isrun through the device for 2.50 min, 10.2 mL of water-saturated H2 (g) is collected. Thetemperature of the system is 25.5 degrees Celsius, and the atmospheric pressure is 768 torr.

What is thmagnitude of the current in amperes?
