Question
Chapter 21, Problem 15QAP
Interpretation Introduction
Interpretation:
Interpret secondary structure of protein collagen.
Concept Introduction:
Protein is a long chain of polypeptide in which numbers of amino acids are linked to each other to produce a structure known as protein.
Each amino acid consists of carboxyl end and amino group which are joined through peptide linkage to produce dipeptide, tripeptide and polypeptide according to number of amino acids linked to each other.

Propagation of uncertainty. You have a stock solution certified by the manufacturer to contain 150.0±0.03 µg SO42-/mL. You would like to dilute it by a factor of 100 to obtain 1.500 µg/mL. Calculate the uncertainty in the two methods of dilution below. Use the following uncertainty values for glassware:
Glassware
Uncertainty
(assume glassware has been calibrated and treat the values below as random error)
1.00 mL volumetric pipet
0.01 mL
10.00 mL volumetric pipet
0.02 mL
100.00 mL volumetric flask
0.08 mL
Transfer 10.00 mL with a volumetric pipet and dilute it to 100 mL with a volumetric flask. Then take 10.00 mL of the resulting solution and dilute it a second time with a 100 mL flask.
2. Transfer 1.00 mL with a volumetric pipet and dilute it to 100 mL with a volumetric flask.

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.
