A certain reagent is added to a suspension of cells 4/mu m in diameter. These cells have a density of 1.08 g/cm^3, and they are suspended in liquid with a density of 1.00 g/cm^3 and viscosity of 1.0 cp. This reagent causes about half of the cells to form fairly solid aggregates, all of which are 90 mu m in diameter and have density midway between that of the liquid and the cells. How much time is required for all the aggregates to sediment to within 1 cm of the bottom of a vessel filled with suspension that is 0.5 m high? Approximately what fraction of the single cells would have sedimented to this depth in the same amount of time? How much time is required for all the single cells to sediment to within 1 cm of the bottom of the vessel?

Since the gas in your graduated cylinder is a mixture of butane and water vapor, you must determine the partial pressure of the butane, pbutane, alone. to do this, consult a reference and record the partial pressure of the water vapor, pwater, at the temperature you recorded. use the following formula to compute the partial pressure of the butane. pbutane = atmosphere - pwater use the following combined gas law formula and compute the volume that the butane sample will occupy at stp. (hint: convert both temperatures to kelvin.) pbutane x voriginal = pstandard x vfinal troom tstandard use the following ratio and proportion formula to determine the mass of butane needed to occupy a volume of 22.4 l at stp. grams of butane you used “x” grams of butane ml of butane corrected to stp = 22,400 ml compute the theoretical molar mass of butane based on its formula and the atomic masses on the periodic table. compare your experimental results from #3 to the theoretical value of #4, computing a percent error of your findings using this formula: % error = measured value - accepted value x 100 accepted value use the following ratio and proportion formula to determine the mass of butane needed to occupy a volume of 22.4 l at stp. need asap
