(b)Calculate the number of moles of CuSO4 that were in the impure sample of CuSO4(s) . (c) In addition to the number of moles of CuSO4 calculated in part (b) , what other quantity must be measured in order to calculate the mass percentage of CuSO4 in the impure sample of CuSO4(s) ?

The questions are incomplete

Explanation:

(b) This question is incomplete. However to calculate the number of moles of CuSO₄ present in the impure sample. The formula below can be used;

number of moles = mass of CuSO₄ present in the impure sample ÷ molar mass of CuSO₄

(c) This question is also incomplete. However, to calculate the mass percentage of CuSO₄ present in the impure sample of CuSO₄, the formula below can be used.

Mass percentage of CuSO₄ =

mass of CuSO₄ present in the impure sample/mass of impure CuSO₄ × 100

Thus, the mass of the impure sample must be measured also since the actual mass of the CuSO₄ present in the impure sample must have been measured before calculating the number of moles.

the electron configuration that you gave me has 16 electrons ergo it has 16 protons ergo it is the element sulfur.
