... trip and measure its length using the MEASURY THING. Record the results. 7. Clean the Test Tube and repeat this experiment twice. 8. Now do repeat the 7 steps above, using 0.5 Molar Sucrose Solution and then 1.0 Molar Sucrose Solution.
To generate reliable and precise results I will use solutions whose molarity has been determined to one decimal places and measure the mass of my potato samples in grams to the same degree of accuracy.
My results are therefore likely to be accurate to within ± 0.005 g which represents a mass 100th the size of my sample. This mean that I will be 99% confident my measurements are precise.
To eliminate, as far as possible, any errors in my procedure I intend to set up each concentration 3 times. This will hopefully allow me to increase th ...
