Metal Rod Procedure & Calculations

Using a balance

Using a balance, place weigh paper on it and zero the scale. Using that measure a metalrod and record measurement. Then take a 25 mL graduated cylinder and fill about half withwater then record the exact volume. In the graduated cylinder add the metal rod, record the newvolume.To calculate the density of a metal rod, the mass and volume of the metal rod needed tobe found. The volume was calculated by subtracting the volume of the water in a graduatedcylinder with the metal rod, by the volume of the initial water. Using that calculated volume andthe mass found by using the balance you will use the density equation d=m/v where v is equalto the volume of the cylinder, m is equal to the mass of the metal rod and d equals the density ofthe metal rod.Sugar Content Procedure & CalculationsTo begin use a 125 mL Erlenmeyer flask and fill it with about 50 mL of 2% sugar liquid.Measure a 50 mL beaker by using a balance, record value. Then using that 50 mL beaker and a10 mL volumetric pipette plus pipette filler, fill the 10 mL volumetric pipette and filler to 10.00 mLof 2% sugar. Put the liquid in the volumetric pipette into the 50mL beaker that was previouslymeasured. Next measure and record the mass of the beaker using the balance. This processwas repeated 2 more times for a total of 3 trials Then using a cranberry juice using the samesteps and doing a total of 3 trials. Once more do the same steps using root beer for a total of 3trials.To calculate the sugar content for the cranberry juice and the root beer, first calculatethe average density of the celebration standard, 2% sugar. This is found by first subtracting thefinal mass of both the beaker and the liquid by the initial mass of just the beaker to find theliquid's mass of the 2% sugar. Then using the density equation d=m/v where d= density, v=volume and m=mass. Use the mass found by subtracting the final and initial and divide it bythe constant 10 mL of 2% sugar. Then repeat this for each trial, it was repeated 2 more times fora total of 3 more times. Using the 3 density’s find the average by adding all the desitys of 2%sugar and dividing it by 3. These calculations where completed for both the cranberry juice andthe root beer. After calculating each of those using the calibration standard averages of theclass for the sugar % create a plot graph and a trend line (Figure). Using the trend line equationwhere x represents the % sugar content and y represents the density in g/mL, substitute theaverage density of both cranberry juice and the root beer into the y of the trend line equation.Then solve for x, the % sugar content.Data

Using that measure a metalrod and record measurement.
