You and your lab partner are asked to determine the density of an aluminum bar. The mass is known accurately (to four significant figures). You use a simple metric ruler to measure its dimensions and obtain the results for Method A. Your partner uses a precision micrometer and obtains the results for Method B The accepted density of aluminum is 2.702 g/cm3. (a) Calculate the average density for each method. Should all the experimental results be included in your calculations? If not, justify any omissions. (b) Calculate the percent error for each method's average value. (c) Calculate the standard deviation for each set of data. (d) Which method's average value is more precise? Which method is more accurate?
According to the Official Rules of Baseball, a baseball must have a circumference not more than 9.25 in or less than 9.00 in and a mass not more than 5.25 oz or less than 5.00 oz. What range of densities can a baseball be expected to have? Express this range as a single number with an accompanying uncertainty limit.
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.)
When a large or small number is written in standard scientific notation, the number is expressed as the product of a number between 1 and 10, multiplied by the appropriate power of 10. For each of the following numbers, indicate what power of 10 would be appropriate when expressing the numbers in standard scientific notation. a. 84,961,306 b. 0.4870 c. 0.000033812 d. 3,890,406,000,000

The first instrument we will use in lab is called a graduated cylinder. A graduated cylinder reads starting from zero at the bottom and goes up as liquid fills it. Keep in mind that you should always estimate one digit further than what is marked on the device to preserve your significant figures. For example, if the device has 1.0 mL increments, the measurement can be estimated to the second decimal place. For the graduated cylinder below, what would be the correct volume reading considering that the markings are in milliliters? Hint: What are the increments of measurement on the graduate cylinder below? -60 -50 -40 -30 -20
