What Is Density In Minerals

Density and Specific Gravity - Practice Issues

Y'all can download the questions (Acrobat (PDF) 25kB Jul24 09) if you lot would similar to work them on a separate sheet of newspaper.

Calculating densities of rocks and minerals

Trouble 1: You lot have a stone with a book of 15cm³ and a mass of 45 g. What is its density?

Problem 2: You have a different rock with a book of 30cmⁱⁱⁱ and a mass of 60g. What is its density?

Problem three: In the above ii examples which rock is heavier? Which is lighter?

Trouble 4: In the above 2 examples which rock is more dense? which is less dense?

Problem 5: You lot make up one's mind yous want to carry a boulder home from the beach. It is 30 centimeters on each side, and so has a volume of 27,000 cmⁱⁱⁱ. It is made of granite, which has a typical density of ii.eight thousand/cm³. How much will this boulder weigh?

rip rap

Problem half dozen: Rocks are sometimes used along coasts to forestall erosion. If a rock needs to weigh two,000 kilograms (about 2 tons) in social club non to be shifted by waves, how large (what volume) does it need to be? Y'all are using basalt, which has a typical density of 3200 kg/m³

A pyrite cube

Trouble vii: A gilt-colored cube is handed to y'all. The person wants you to buy information technology for $100, saying that is a gold nugget. Yous pull out your former geology text and look upwards gold in the mineral table, and read that its density is 19.iii g/cmⁱⁱⁱ. You mensurate the cube and detect that it is 2 cm on each side, and weighs 40 g. What is its density? Is it gold? Should you buy it?

Calculating Specific Gravity of Rocks and Minerals

Problem viii: You take a sample of granite with density 2.eight g/cm^three. The density of water is 1.0 grand/cm^three. What is the specific gravity of your granite?

Trouble 9: You have a sample of granite with density 174.8 lbs/ft³. The density of water is 62.4 lbs/ft^three. What is the specific gravity of the granite now?

TAKE THE QUIZ!!

I think I've mastered density and I am fix to take the quiz!
