A chemist dissolves 0.099 g of CuSO4 · 5 H2O

in water and dilutes the solution to the mark
in a 500-mL volumetric flask. A 28.9-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?
Answer in units of M.
**answer: .000046**

SECOND PART:
To prepare the second 500 mL of solution
directly, what mass of CuSO4 · 5 H2O would
need to be weighed out?
Answer in units of mg.

1 answer
