(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.

(a) To identify a liquid substance, a student determined itsdensity. Using a graduated cylinder, she measured out a 45-mLsample of the substance. She then measured the mass of thesample, finding that it weighed 38.5 g. She knew that the substancehad to be either isopropyl alcohol (density 0.785 g/mL)or toluene (density 0.866 g/mL). What are the calculated densityand the probable identity of the substance? (b) An experimentrequires 45.0 g of ethylene glycol, a liquid whose densityis 1.114 g/mL.
