Question
(a) Use the following theoretical density values for copper and zinc metals (in g/mL) and the experimental density values you obtained in Question 12 to determine the percent error in each of your experimental values.
Density of copper (theoretical) ρCu = 8.94 g/mL
Density of zinc (theoretical) ΡZn = 7.14 g/mL
The equation for percent error is: "%Error"=|"Experimental value - Theoretical value" /"Theoretical value" |×100
Show your work and calculated values, include units.
(b) Suggest possible reasons for differences between the experimental and theoretical density values for each metal.
14. Describe any issues you had with the virtual lab, or any unrealistic situations you thought were funny. Also describe the benefits and deficiencies you seen in virtual labs compared to real lab experiences.
