Question

Chapter 23, Problem 1SAQ

Interpretation Introduction

Introduction: A metal that is found inside the earth in the form of mineral or ores is not in pure elemental state and metal is to be extracted from it.

Expert Solution & Answer

Answer to Problem 1SAQ

Correct answer: Option (a) is correct.

Explanation of Solution

Justify reason for correct statement:

Gold occurs in elemental state with some small particles and other substances. Hence, option (a) is correct.

Justify reason for incorrect statements:

Other metals like titanium, chromium, and iron are found as either ores or minerals.

Titanium is found as oxides in ilmenite and rutile.

Iron is found as oxide in hematite.

Chromium is found as oxide in chromite.

Thus, these cannot be obtained in pure elemental state similar to that of gold.

Hence, options (c), (b), and (d) are incorrect.

Conclusion

Gold is naturally found in elemental state.

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.
