What volume of 1.0 mol/L solution of CuS can be made from 23.9 g of CuS?
Themolar concentration of the solution can be found for the formula C = n / V(solution); The amount of substance can also be found for the formula: n = m / M For CuS molar mass will be: M(CuS) = 64 + 32 =96 g/mol; n(CuS) = 29.3 g / 96 g/mol = 0.305 moles; So the volume of solution will be V(solution) = n /C; V(solution) = 0.305 moles / 1 mol/L = 0.305 L So the volume of solution is 0.305 L or 305 ml.
