Or you may want to know how fast Chlorox kills bacteria. If you add some Chlorox to a culture and count the surviving bacteria at suitable intervals you can plot killing the killing curve and determine whether the killing is single hit or higher order. It will

Laboratory Measurements and Density Objectives: A. To determine the density of Aluminum (lit. value = 2.7 g/cm3) by determining its mass‚ and measuring its volume by dimensional analysis and water displacement. We will also examine the % error in our determination based on the literature value. B. To determine the mass and diameter of select ball bearing. Plot graphs of mass vs. diameter‚ mass vs. surface area‚ and mass vs. volume. Afterwards use slop of the mass vs. volume graph to determine density
