How would you prepare the following solutions? Unless stated otherwise, assume that the solvent is purified water and that you will dissolve the solute in a lesser amount of solvent and then “bring the solution to volume”. Show your math and use proper units.

CuSO4 FW 159.61

NaCl FW 58.44

CaCl FW 111.0

Na2SO4. 10H2O FW 322.04

11. 250 ml 1 mM CuSO4

12. 500 ml 0.25M NaCl

13. 100 ml 20mM CaCl

14. 10 ml 1 M Na2SO4

15. 50 ml of 3:2:1 ethylene:chloroform:isoamyl alcohol

Thank you so much.
