Answer:c
Explanation: atoms make matter
D should be the answer since there are tons of moons in our solor systtem
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
