Verina Atalla September 20, 2009 Renu Jain Chemistry 1111 Determination of the density of a solid and liquid 1) Which is more precise, the density derived from the calculated volume or the  density derived from the measured volume?  Explain you answer in detail.  The one that is more precise is the calculated volume because the  uncertainty level of the calculated value was far less than the measured  value.  The calculate density was 3.34x10 -2  and for the measured it was  8.6x10 -2 .  I felt like the calculated value was less prone to human error  because the vernier caliper was much more precise than the telling of the  volume of the graduated cylinder, so therefore is decreased the likelyhood of  uncertainty which means that the calculated volume is more precise.      2) How would you determine the density of a gas? Since Density equals mass divided my volume, you would need to find
