A e
9. What is the mass of a sample of aluminum which has a density of 2.70 g/cm 3 and a volume of 33.0 cm 3 ?
Answer :
10. What is the volume of a sample of lead which has a mass of 44.5 g and a density of
11.4 g/cm 3 ?
Answer :
11. Compare the Kelvin and Celsius temperature scales using the following reference points :
Kelvin Celsius
_______ absolute zero ________
_______ freezing point of water ________
_______ boiling point of water ________

12. Convert the following temperature measurements between the Celsius and Kelvin scales : a. _____ K = 20.0 ºC b. _____ ºC = 40 K c. _____ K = 45.2 ºC d. _____ ºC = 12.0 K k ilo- = 1000 centi- = 1/100 milli- = 1/1000
Conversions
1 kg = 1000 g 1000 mg = 1 g 1 mL = 1 cm 3
1 km = 1000 m 100 cm = 1 m
1 kL = 1000 L
1000 mm = 1 m 1 L = 1 dm
1000 mL = 1 L 1 cm = 10 mm
