D, because matter does not change in space but unlike gravity, which changes, matter, is the mass of it, which will stay the same unless there is a chemical change or, physical change, but not in this case, so the answer you are looking for is D. hope this enlarged your understanding and knowledge.
molarity of the CuSO₄ solution = 0.68 moles/L
Explanation:
The formula for molar concentration is:
molar concentration (molarity) = number of moles / solution volume (L)
number of moles = mass / molecular weight
number of moles of CuSO₄ = 12.304 / 159.6
number of moles of CuSO₄ = 0.07709 moles
molar concentration of the CuSO₄ solution = 0.07709 / 0.1127
molar concentration of the CuSO₄ solution = 0.68 moles/L
