Problem
Electrolysis of a molten chloride of metal X is carried out with a steady current of 5.00 A for 25.0 min, producing 1.48 g of X at the cathode. If the metal ions in the melt carry a +3 charge, what is the approximate atomic mass of X? (Faraday constant = 9.65 × 10⁴ C mol⁻¹)
(a) 19.0g mol−1
(b) 57.1g mol−1
(c) 38.1g mol−1
(d) 171g mol−1
