Chapter 1, Problem 101AE
The density of an irregularly shaped object was determined as follows. The mass of the object was found to be 28.90 g ± 0.03 g. A graduated cylinder was partially filled with water. The reading of the level of the water was 6.4 cm3 ± 0.1 cm3. The object was dropped in the cylinder, and the level of the water rose to 9.8 cm3 ± 0.1 cm3. What is the density of the object with appropriate error limits? (See Appendix 1.5.)

Take the mass measurement with nitrogen (28 dalton or atomic mass units per molecule) and the mass measurement with helium (4 daltons per atom) and use the difference between the measured masses to find the mass of 1 dalton (one atomic mass unit) in grams. The standard value of the dalton is 1.66053906660×10−27 kg with an uncertainty of ±50 in the last two figures.
Can you identify the sources of error in your measurement?
A student gently drops an object weighing 16.5 g into an open vessel that is full of ethanol, so that a volume of ethanol spills out equal to the volume of the object. The experimenter now finds that the vessel and its contents weigh 10.5 g more than the vessel full of ethanol only. The density of ethanol is 0.789 g / cm^3. What is the density of the object?
The shattered glass case at the scene of a jewelry store robbery was determined to be made of potash borosilicate glass, which has a density of 2.162.16 g/mL. A 4.0744.074 g glass fragment was recovered from a suspect's clothing. When the fragment was placed into a graduated cylinder filled with water, 1.341.34 mL of the water was displaced. Calculate the density of the glass fragment.

(a) 96,485 J/C to three significant figures (b) 2.9979 g/cm3 to three significant figures (c) 0.0597 mL to one significant figure (d) 6.626 1034 kg to two significant figuresarrow_forwardThe label on a bale of mulch indicates a volume of 1.45 ft3. The label also states that the mulch in the bale will cover an area of a garden 6 ft 6 ft to a depth of 1 in. Account for the discrepancy in the given volumes.arrow_forwardOn October 21, 1982, the Bureau of the Mint changed the composition of pennies (see Exercise 120). Instead of an alloy of 95% Cu and 5% Zn by mass, a core of 99.2% Zn and 0.8% Cu with a thin shell of copper was adopted. The overall composition of the new penny was 97.6% Zn and 2.4% Cu by mass. Does this account for the difference in mass among die pennies in Exercise 120? Assume the volume of the individual metals that make up each penny can be added together to give the overall volume of the penny, and assume each penny is the same size. (Density of Cu = 8.96 g/cm3; density of Zn = 7.14 g/cm3).arrow_forward
