Purpose: The purpose of this experiment is to determine the unknown concentration of a solution by effectively preparing series of standard solutions and accurately measuring their densities. Procedure: 1. Weigh 10 mL graduated cylinder 2. add 10 mL distilled water to cylinder and weigh and record 3. add 10 mL of unknown stock solution and weigh 4. put 3 mL of stock solution and then fill to 10 mL with distilled water and weigh 5. put 5 mL of stock solution and then fill to 10 mL with distilled water and weigh 6. put 7 mL of stock solution and then fill to 10 mL with distilled water and weigh 7. put 10 mL of unknown solution in cylinder and weigh 8. find density of each (2-7) and plot points 2-6 on graph to make standard curve 9. plot point 7 on graph and find concentration of the unknown solution Results and Calculations: Raw Data Chemistry 211-211-204 Density: anam ahmad Conc_stockVi_AVf_AVi_B Vf_B Vi_CVf_Cm_stockV_stockm_A V_A m_B V_B m_C V_C m_waterV_waterm_unkwnV_unkwn 3 3.1 10 5.2 10 7.1 10 10.806 1010.398 1010.609 1010.867 10 9.957 10 10.582 10 3 3 10 5 10 7 10 10.965 1010.264 1010.428 1010.687 10 9.72 10 10.7 10 3 3 10 5 10 7 10 11.005 9.9 10.269 10.110.483 9.8 10.695 10 9.877 10.2 10.093 9.9 3 3 10 5 10 7 10 11.238 1010.427 10.110.685 1010.963 9.9 10.032 10.2 10.385 10 3 3 10 5 10 7 10 10.994 1010.258 1010.515 1010.271 10 10.008 10 10.506 10 3 3 10 5 10 7 10 9.897 9.99 10.378 10.0110.718 9.98 10.808 9.99 10.997 9.98 10.525 10.01 3 3 10 5 10 7 10 10.854 10.05 10.187 10.0410.42310.13 10.565 10.078 9.752 10.011 10.384 10 3 3 10 5 10 7 10 10.829 9.9 10.025 9.910.362 9.8 10.649 10.1 9.7 9.9 10.072 9.9 3 3 10 5 10 7 10
