WebSep 25, 2006 · An example would be 31.75 mL – 1.325 mL = 30.425 mL. In order to find the density, I simply divided the mass found by the volume found. For example, 30.0035 g divided by 30.425 mL equals 0.9861 g/mL. To find the average density, I added the three densities I found, then divided that total by three to find the average. WebThe determination of fluid density and viscosity using most cantilever-based sensors is based on changes in resonant frequency and peak width. Here, we present a wave propagation analysis using piezoelectrically excited micro-cantilevers under distributed fluid loading. The standing wave shapes of microscale-thickness cantilevers partially …
WebNov 13, 2013 · Assuming the solution has a density of 1.00 g/mL, determine the mass of the solution. Record the mass of the cup and the solution it contains in your notebook. Do NOT place a wet cup or a cup filled with liquid on the balance! Helpful hint: use the density and the volume to calculate the mass. Doing so can cause severe damage to the balance.
