1.. 2. 3. 4. 5. 6. 7. 8. EXPERIMENT 1 PRE-LABORATORY QUESTIONS 10. LabSection What are the basic units of length, mass, volume, and temperature in the SI system? A liquid has a volume of 3.70 liters. What is its volume in mL? in cm³? If an object weighs 1.47 g, what is its weight in mg? Why should you never weigh a hot object? Why is it necessary to calibrate a thermometer and volumetric glassware? What is precision? What is the density of an object with a mass of 1.663 g and a volume of 0.2009 ml? Weighing an object three times gave the following results: 9.2 g. 9.1 g, and 9.3 g. Find the mean weight and the standard deviation from the mean. DNA is approximately 2.5 nm in length. If an average man is 6 ft. tall, how many DNA molecules could be stacked end to end in an average man? An object weighs exactly five grams on an analytical balance that has an accuracy of 0.1 mg. To how many significant figures should this weight be recorded?
