Calculate the mass of silver deposited when a current of 4.6 A is passed through a solution of a silver salt for 90 minutes. [Ag 108, 1 Faraday = 96,500 C)
Calculate the mass of silver deposited when a current of 4.6 A is passed….
Mass of silver deposited (in grams) = (Current in Amperes × Time in seconds × Atomic mass of silver) / (1 Faraday)
Given:
Current = 4.6 A
Time = 90 minutes = 90 × 60 seconds = 5400 seconds
Atomic mass of silver (Ag) = 108g/mol
1 Faraday = 96,500C
Substituting the values to calculate the mass of silver deposited:
Mass of silver deposited = (4.6 A × 5400 s × 108 g/mol) / 96,500 C
Mass of silver deposited ≈ (2,682,720 g·s/mol) / 96,500 C
Mass of silver deposited ≈ 27.8g
