Suppose that you repeated the reaction between copper(II) sulfate and sodium sulfide using

6.30mL

of

0.170MCuSO_(4)

and\

13.70mL

of

0.170MNa_(2)S

. Then, you decanted the resulting supernatant from the copper(II) sulfide that precipitated, and\ added

10.0mL

of the test solution to the supernatant.\ Determine the mass of copper(II) sulfide that precipitated. The molar mass of copper(II) sulfide is

95.611(g)/(m)ol
