Term Best description
Eriochrome Black T EBT
Starting color, before titration Pale purple-pink color
Molecule that has a high affinity for metal ions Chelating agent
Ethylenediaminetetracetic acid EDTA
Color at the completion of titration Blue-gray color
The Percent error in the calculation of densities of the metal during experiment is 0.03 %
<h3>What is Percentage error?</h3>
Percent error is the difference between estimated value and the actual value in comparison to the actual value and is expressed as a percentage.
Percent error = [Experimental value - Theoretical value] / Theoretical value x 100%
Percent error = 7.83 -7.86 / 7.86 x 100
= 0.03 %

Answer:
Please see the attached picture for the full solution.
Explanation:
Alternatively, for problem #2, you can find the density in g/ml first then convert it to kg/m³.
Density of liquid
= 45 ÷45
= 1 g/ml
= 1000 kg/m³
