These uncertainties are shown to propagate through the calculation resulting in an uncertainty associated with the determination of density. Theory. 0 The density of a homogeneous material is defined as the mass per unit volume, or. P= = (1) The units associated with the density are kg/m3, g/cm3, and slug/ft3. ...

Measuring density with (un)certainty Lab objectives. Scientific knowledge. Students will demonstrate that as the volume of a substance increases, the mass increases proportionally. This proportionality is known as density. Lab skills. Students will use a spreadsheet to calculate values based on measurements made of various objects.

Calculate the % uncertainty in your density. The overall % uncertainty is the sum of the relative (percent) uncertainties of the measurements. For example, student X obtains an average mass of 7.973 g ± 0.002 and an average volume of 10.03 mL ± 0.05 for her unknown liquid. The density of her liquid is.
