Interpret from the given structure as same compound and constitutional isomer. Concept Introduction: Constitutional isomers are the isomer with same molecular formula but having different structure due to different arrangement of groups on principal chain. The atoms are linked to the principal chain in different arrangement to give a new structure with same molar mass. Each different structure having different properties such as melting point or boiling point etc.

Question

What is the average mass of the 10 pennies? Report your value with correct significant figures. What is the error (uncertainty) associated with each mass measurement due to the equipment? What is the uncertainty associated with the average value? Note that the uncertainty of the balance will propagate throughout the calculation. What is the standard deviation of the 10 mass measurements? Explain the difference between the propagated uncertainty and the standard deviation. Which number would you use to describe the uncertainty in the measurement? Calculate the total mass of the pennies with associated uncertainty. Calculate the average density of a penny based on these data. Propagate the uncertainty values for both mass and volume in your calculations.
