Question

Total charge on 1 mole of a monovalent metal ion is equal to
(a) 9.65 × 10⁴ coulombs
(b) 1.6 × 10⁻¹⁹ coulombs
(c) 6.2 × 10¹⁸ coulombs
(d) None of these

Answer 1

I think the answer is a

Answer 2

Answer:

a) 9.65 × 10⁴ coulombs

Explanation:

A monovalent metal may refer to any monovalent ion, or an atom, ion, or a chemical group with a valence of one, which therefore can form one covalent bond. Thus, a monovalent element is an element that has a valence of one, for example the hydrogen.

One monovalent metal ion is equivalent to charge of -

= N electrons = 96500 coulombs  or 1 Faraday

= 9.65 × 10⁴

Thus, the total charge on 1 mole of a monovalent metal ion is equal to 9.65 × 10⁴  coulombs.
