Answer to Question #22087 in Inorganic Chemistry for khadijah

Question

What volume of 1.0 mol/L solution of CuS can be made from 23.9 g of CuS?

Answer 1

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.
