Convert the following numbers into proper scientific notation: a) 463,000 = _________ b) 56 = ________ c) .0000078 = __________ d) 0.950 = __________ e) 108.75 x 10 4 = _________ f) .985 x 10 8 = ____________ g) 934.1 x 10 -9 = ____________ 6. Convert the following numbers into ordinary notation: a) 3.58 x 10 7 = ___________ b) 4.54 x 10 2 = ___________ c) 5.47 x 10 0 = ___________ d) 4.44 x 10 -3 = ___________ e) -5.74 x 10 3 = ___________ 7. Find the answers to the following without using a calculator. Show all work and circle your final answer! a) 5.0 x 10 4 * 1.0 x 10 6 e) 4.0 x 10 7 * 3.0 x 10 8 b) 6.0 x 10 7 + 2.0 x 10 6 f) 6.0 x 10 -5 / 3.0 x 10 2 c) 4.0 x 10 4 / 2.0 x 10 2 g) 8.0 x 10 -5 + 1.0 x 10 -6 d) 8.0 x 10 3 – 5.0 x 10 2 h) (8.0 x 10 6 - 5.0 x 10 5 ) / 1.0 x 10 3 8. a) During lunch last week, you were served a mysterious substance as your beverage. You take a sample back home with you, and find out that the mass of the liquid is 458 grams and the volume is 446.8 milliliters. In the space below, calculate the density of this mysterious object – use the method your teacher taught you in class to calculate the density! b) Using Figure 2.8 on p. 36 of your textbook, identify what this mystery substance is (NOTE: it is a clear substance) 9. Find the mass of an object that has a density of 0.92 grams per milliliter and a volume of 55.7 milliliters. Again, use the method shown in class to do this problem!
10. What is the volume of a liquid that has a mass of 24.2 grams and a density of 1.2 grams per milliliter? Use the method shown in class to solve this problem. 11. From the lab last week in class, you remember that the density of sand is equal to 1.60 grams per milliliter. If you weigh out 20. grams of sand, what will the volume be? 12. a) Using the table on p. 36 of your textbook, list the solids that will sink in water. b) Which solids listed in the same table will float in ethyl alcohol? 13. Whoa! Jaden can bench 136 kilograms! How many ounces is this equal to (2.2 pounds = 1 kilograms; 16 ounces = 1 pound)? Use conversion factors to solve this problem in the space below. 14. Your friend from Switzerland needs help. She just moved here, and needs to know what 60 miles per hour is equal to in meters per second (the unit of choice in her country) so that she doesn’t speed on the beltline. Using conversion factors found on p. 16 of your packet, convert 60 miles per hour into meters per second in the space below. 15. A fictional <strong>Monona</strong> <strong>Grove</strong> High School chemistry student was asked to gather data on the density of mercury (this is fictional because, unfortunately, mercury is poisonous and we don’t have any). She wanted to make sure she repeated her measurements 3 times to get good data. Below is her data table: Repetition Mass Volume Density Percentage Error 1 25.2 g 1.73 mL 14.6 g/ml 2 24.7 g 1.68mL 14.7 g/ml 3 23.7 g 1.61 mL 14.7 g/ml a) What is the accepted value for the density of mercury (see p. 36 of your textbook). b) Would you say the density data are precise? Explain. c) Would you say the density data are accurate? Explain. d) Fill in the last column of the data table by calculating the percent error for each repetition.
