Textbook Question

Chapter 1, Problem 37E

To identify a liquid substance, a student determined its density. Using a graduated cylinder, she measured out a 45-mL sample of the substance. She then measured the mass of the sample, finding that it weighed 38.5g. She knew that the sub-stance had to be either isopropyl alcohol (density 0.785g/mL) or toluene (density 0.866g/mL). What are the calculated density and the probable identity of the substance?
An experiment requires 45.0 g of ethylene glycol, a liquid whose density is 1.114g/mL. Rather than weigh the sample on a balance, a chemist chooses to dispense the liquid using a graduated cylinder. What volume of the liquid should he use?
Is a graduated cylinder such as that shown in figure 1.12 likely to afford the accuracy of measurement needed?
A cubic piece of metal measures 5.00 cm on each edge. If the metal is nickel, whose density is 8.90g/cm³, what is the mass of the cube?

Q1. The net potential energy between two adjacent ions, EN, is represented by A В E N pn where EN is the net energy in Joule (J), A and B are constants with values of 1.436 J.nm and 7.32 × 106 J.nm, r is the interatomic distance between the two ions in nanometer (nm), and n is a positive number with a value of 8.

A researcher has developed a new analytical method to determine the percent by mass iron in solids. To test the new method, the researcher purchases a standard reference material sample that is 2.85% iron by mass. Analysis of the iron standard returns values of 2.75%, 2.89%, 2.77%, 2.81%, and 2.87%. Are the results of the new method significantly different from the standard reference sample? (Hint: Use Confidence Interval)

The mass of magnesium used in this experiment is critical to determining the moles of hydrogen gas generated. The analytical balances used in Chemistry 1A labs are very sensitive to point that touching materials with your fingers before measuring them can affect the measurements. The balances are sensitive enough to detect dirt and oils from your fingers transferred to the magnesium. Would your experimental value of R increase or decrease if the mass of magnesium measured was artificially high due the touching it with your hands? Increase Decrease
