Mass in grams of copper deposited by passing 9.6487 A current through a voltmeter containing copper sulphate solution for 100 seconds is (Given : Molar mass of $Cu : 63 g mol^{- 1}, 1 F = 96487 C$ )NEET 2024

Options:

Answer:

Solution:

$Cu^{2 +} (aq) + 2 e^{-} \to Cu (s)$ $Mass of Cu deposited (w) = \frac{M \times i \times t}{n F} = \frac{63 \times 9.6487 \times 100}{2 \times 96487} = 0.315 g$
