Among the given fatty acids, the fatty acid that is an omega-6 fatty acid has to be predicted. Concept introduction: There are two types of unsaturated fatty acids: omega-3 fatty acids and omega-6 fatty acids. Omega-6 fatty acids are the type of unsaturated fatty acids that have the last double bond at the sixth position from its methyl group. Omega-3 fatty acids are the type of unsaturated fatty acids that have the last double bond at the third position from its methyl group.

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.
