Density of Zinc: Consider the data and results from the density of zinc determination. Now focus on the average absolute error associated with the calculated average density of zinc. Which measurement contributes the most relative error to this value? Given that measurement and its associated absolute error, is the calculated average absolute error reasonable and why? What aspect of the experiment limited the measurements the most?In an experiment with an Ostwald Viscometer, the times of flow of water and toluene are 45 s and 32.9 s respectively at 30°C. The density of water is 1.002 g/cc. Calculate the density of the toluene in g/ml. (µwater = 0.8916 %3D cP, utoluene = 0.5239 cP) Use 4 decimal places. 0.8853 0.8053 O 0.8080 O 0.8882
- Explain the difference between random sampling and haphazard sampling as used in Analytical chemistry.A student calibrated a eudiometer by first recording the mass of the empty eudiometer followed by filling the eudiometer to the 50.00 mL line with deionized water at 22°C and recorded the mass. The mass of water was 49.012 g. What measured reading from the eudiometer would correspond to a true volume of 47.89mL?Calculate the value of n if idmax= 7.008×10-6A.
