- Determine the final concentration of each of the following solutions after 20mL of water has been added. A. 30mL of 5 M NaCl solution B. 125mL of 2 M CaO solution C. 200mL of 4.4 M MgCl2 solution D. 20 mL of 0.01 M AgNO3 solutionarrow_forwardCHEMISTRY 1110L LAB REPORT: PROPERTIES OF SOLUTIONS Part One (Do calculations on the back of this sheet, prior to lab!) 1. In order to prepare 50.0 mL of 0.100 M NaOH you will add 2. In order to prepare 50.0 mL of 0.200 M 3. In order to prepare 50.0 mL of 0.150 M 4. In order to prepare 50.0 mL of 0.100 M HC₂H3O2 you will add mL of 1.00 M HC₂H₂O₂ to HCl you will add H₂SO4 you will add 5. In order to prepare 40.0 mL of 0.100 M NH3 you will add 6. In order to prepare 50.0 mL of 0.100 M NaCl you will add___ grams of NaCl to mL of water. 7. In order to prepare 50.0 mL of 0.100 M C12H22O11 (sucrose) you will add grams of C12H22O11 to mL of water. NOTE: The final volume is the sum of the concentrated solution plus the volume of added water. When making solutions from solids, since the solid dissolves in the water with minimal volume change, the volume of the final solution is the amount of water you need to use. Part Two 8.
