Question

calculate the mass of copper metal produced during the passage of 2.5A of current through a solution of cuso4 for 40 min.(m.m. of cu=63.5gm/mol)​

Answer 1

Answer:

Explanation:

Charge on one ion of N3-

= 3 × 1.6 × 10-19 coulomb  

Thus, charge on one g-ion of N3-

= 3 × 1.6 10-19 × 6.02 × 1023

= 2.89 × 105  coulomb
