Asked by Neftali
A chemist dissolves 0.095 g of CuSO4 · 5H2O
in water and dilutes the solution to the mark
in a 500-mL volumetric flask. A 39.7-mL
sample of this solution is then transferred to a
second 500-mL volumetric flask and diluted.
What is the molarity of CuSO4 in the second
solution?

Find M in the first one first.
mols CuSO4.5H2O = grams/molar mass = ?
M = mols/0.500L = ?M
In the second flask, we have
?M from first x (39.7/500 = xM.
mols CuSO4.5H2O = grams/molar mass = ?
M = mols/0.500L = ?M
In the second flask, we have
?M from first x (39.7/500 = xM.
