A constant current of 0.912 a is passed through an electrolytic cell containing molten mgcl2 for 22.5 h. what mass of mg is produced

Calculation ,

constant current ( I ) = 0.912 A (given )

time ( t ) = 22.5 h = 81000 sec

molar mass of Mg = 24.31 g/mol

number of electron involved in reaction 2 ( known )

calculation of mass ( w ) = molar mass × I × t / nF =

( w ) = 24.31 g/mol × 0.912 A × 81000 sec / 2 × 96500 = 9.35 gram
