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 3.50 min , 13.5 mL of water-saturated H2(g) is collected. The temperature and pressure of the system are 25 âC and 715 torr.
The vapor pressure of water changes with temperature, as shown here.
T (âC) P (torr)
21 18.7
22 19.8
23 21.1
24 22.4
25 23.8
26 25.2
27 26.7
28 28.4
29 30.0
30 31.8
