Under normal conditions, describe how increasing the temperatures effects the solubility of a typical salt

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.

If the specific heat of a metal is 0.850 j/g °c, what is its atomic weight?
