An electric current is passed through a silver voltameter connected to a water voltameter. 0.324 g of silver was deposited on the cathode of the silver voltameter. The volume of oxygen evolved at NTP is :
Text Solution
Verified by ExpertsThe correct answer is:
B
Mass of Ag deposited = 0.324 gm
equivalent of Ag deposited = 
= 3 × 10 –3
⇒ 3 × 10 –3 moles of electrons are transfered.
moles of O 2 produced = 
× 3 × 10 –3
vol. of O 2 produced at STP = 
× 3 × 10 –3 × 22400 ml = 5.6 × 3 = 16.8 ml.
