Question #22087

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

Expert's answer

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.

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.
