. What is its density?

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
