Density is found by dividing mass over volume: d=M/V. In this problem, we know the density, and the mass. Solve the general equation for volume, then enter the values from the problem and evaluate: d=m/v [multiply v to both sides, then divide d from both sides]
v=m/d v=83.8g/(2.33g/cm³) v=35.965 cm³ v=36.0 cm³ to three significant figures (since your given information only has 3 sig figs)
the process for refining a metal in an electrolytic cell, in which the impure metal is used as the anode and the refined metal is deposited on the cathode.
