A student designs an ammeter (a device that measures electrical curent) 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 3.50 min, 13.0 mL of water-saturated H₂(g) is collected The temperature and pressure of the system are
25 C and 715 torr.
