Chapter 18, Problem 151(choose chapter or problem)
Three electrochemical cells were connected in series so that the same quantity of electrical current passes through all three cells. In the first cell, 1.15 g chromium metal was deposited from a chromium(III) nitrate solution. In the second cell, 3.15 g osmium was deposited from a solution made of Osn and nitrate ions. What is the name of the salt? In the third cell, the electrical charge passed through a solution containing X2 ions caused deposition of 2.11 g metallic X. What is the electron configuration of X?
