The current produced is
Time is minutes.
Mass of metal deposited is.
 

Step-by-step explanation

Step 1.

A metal forms the fluoride. The half-reaction corresponding to the electrolysis of molten fluoride is,

 

The valency of metal is 3 because the metal is in oxidation state. Three electrons are transferred.
The molar mass of the metal (M) is calculated by the formula,
.....(1)
Where,
  • is the mass of metal deposited.
  • is number of electrons transferred.
  • is the amount of current.
  • is time.
  • is Faraday's constant  
The conversion of minutes into seconds is done as,
