5. (1.5 points) A 180 pound person carries a 25 pound can of paint up a helical staircase that encircles a tower with a radius of 20 feet. The tower is 90 feet high and makes exactly three complete revolutions. If there is a hole in the can of paint and 9 pounds of paint leaks steadily out of the can during the person’s ascent, how much work is done by the person against gravity in climbing the stairs?

Nacidified solution was electrolyzed using copper electrodes. a constant current of 1.18 a caused the anode to lose 0.584 g after 1.52 ✕ 103 s. given that the charge of an electron is 1.6022 ✕ 10−19 c, calculate avogadro's number. assume that copper is oxidized to cu2+ ions.
