Five students used the same ruler to measure the length of the same pencil. These are their results: 15.34 cm, 15.33 cm, 15.34 cm, 15.33 cm and 15.34 cm. The actual length of the pencil was 16.00 cm. a. Is the data precise? Why or why not? b. Is the date accurate? Why or why not? c. If I measured the length of the pencil to be 15.35 cm, what is my percent error?

1.84 A student was given two metal cubes that looked similar. One was 1.05 cm on an edge and had a mass of 14.32 grams; the other was 2.66 cm on a side and had a mass of 215.3 grams. How can the student determine if these two cubes of metal are the same material using only the data given?
1.21 When a scientist looks at an experiment and then predicts the results of other related experiments, which type of reasoning is she using? Explain your answer.

1.48 A rock is placed on a balance and its mass is determined as 12.1 g. When the rock is then placed in a graduated cylinder that originally contains 11.3 mL of water, the new volume is roughly 17 rnL. How should the density of the rock be reported?
On the planet Xgnu, the most common units of length are the blim (for long distances) and the kryll (for shorter distances). Because the Xgnuese have 14 fingers, perhaps it is not surprising that 1400 kryll = 1 blim. Two cities on Xgnu are 36.2 bum apart. What is this distance in kryll? The average Xgnuese is 170 kryll tall. What is this height in bums? This hook is presently being used at Xgnu University. The area of the cover of this book is 72.5 square krylls. What is its area in square bums?
1.90 A calibrated flask was filled to the 25.00-mL mark with ethyl alcohol and was found to have a mass of 19.7325 g. In a second experiment, 25.0920 g of metal beads were put into the container and the flask was again filled to the 25.00-mL mark. The total mass of the metal plus the alcohol was 43 .0725 g. Describe how to determine the density of the metal sample.
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.)
You are working on a project where you need the volume of a box. You take the length, height, and width measurements and then multiply the values together to find the volume. You report the volume of the box as 0.310m3 . If Iwo of your measurements were 0.7 120 m and 0.52458 m, what was the other measurement?
