Question

A student uses an electronic balance and a graduated cylinder to determine the density of a sample of metal. The shot was found to weigh 116.52 grams. The volume of the water in the graduated cylinder was 8.6 mL before adding the shot and 21.7 mL aftter addition.

- What is the density of the metal shot? Is the metal most likely to be iron, cobalt, or silver? (Dfe=7.86 g/mL; Dco=8.92 g/mL; Dag=10.5g/mL)

-Desricbe the difference between an extensive property and an intensice property of matter and illustrate your explantion with mass, volume, amd density as examples.

- If the student had instead weighed 58.26 grams of the metal shot before adding it to the graduated cylinder containing 8.6 mL of water, what would the volume have been after the addition?

Explanation / Answer

mass of the metal = 116.52 grams

Volume of metal = 21.7-8.6 = 13.1 ml

density of metal = mass/volume = 116.52/13.1 = 8.9 g/ml

metal may the Coblat.

extensiveproperty : the property which depends upon,the quantity of the substance

ex: mass,volume ..etc

intensive property : the property which donot depends upon,the quantity of the substance

ex : density


volume of the metal = 58.26/8.9 = 6.54 ml

volume after addition = 8.6+6.54 = 15.14 ml
