Unformatted text preview: 15.25g 16.4g 16.6g 15.45g Results: 4% 8% 12% 16% Unknown Density of NaCl solutions. (Density= Mass / Volume) 1.13 g/cm^3 1.01 g/cm^3 1.09 g/cm^3 1.01 g/cm^3 1.03 g/cm^3 NaCl Solutions 0.94 0.96 0.98 1 1.02 1.04 1.06 1.08 1.1 1.12 1.14 0.04 0.08 0.12 0.16 unknown Percentages Densities (g/cm^3) Series1 Conclusion: From this lab I am able to conclude that the density of a liquid has nothing to do with the percentage of the NaCl solution. This may be caused by bad data, mainly by human error. For example, my group may have measured the density wrong or mislabeled a data entry. There are many reasons for the data to be incorrect, but hopefully the labs in the future will be more accurate. Questions: I conclude that the percentage of NaCl is 14%. I deducted this because the unknown solution is between 12% and 16%, so I took the average of the two measurements....
