Question

For current 1.5 A in 10 minutes through ZnSO4 deposited

Answer 1

charge = current× time(sec)

current=1.5A

time=10×60=600sec

charge=1.5×600=900C

no of electrons exchanged=2

mole × n of e- = charge/96500

moles=600/193000=0.00310

moles=0.00310

molar mass Zn =65g

mass= moles× molar mass

mass=0.00310×65

mass=0.2015g

I hope this helps ( ╹▽╹ )
