What is the solubility in mol/l of copper(i) sulfide, cu2s? its ksp value is 6.1 × 10-49 .

5.3 × 10⁻¹⁷ mol·L⁻¹

Explanation:

Let s = the molar solubility.

                Cu₂S(s) ⇌ 2Cu⁺(aq) + S²⁻(aq); K_{sp} = 6.1 × 10⁻⁴⁹

E/mol·L⁻¹:                        2s             s

K_{sp}  =[Cu⁺]²[S²⁻] = (2s)²×s = 4s^3 = 6.1 × 10⁻⁴⁹

what are the statements?

explanation:

give me the statements and i'll tell you which is correct

the correct option is c.

isotopes refers to different forms of the same element with the same atomic number but different mass number as a result of difference in their neutron numbers. isotopes have different relative atomic mass but share the same chemical properties.
