n an old movie, an archeologist is shown sprinting off with a gold statue. If the volume of the statue was 3.78L (about the size of 1 gallon of milk), then calculate the mass of gold in pounds. Based upon your result, is what the movie suggested physically resonable? The density of gold is 19.3g/mL

The mass of an unidentified rock is 15.5 grams. Students determine the volume of the rock by placing the rock in a cylinder with water. The students calculate the density of the rock. They determine the identity of the rock based on the density ranges in the table.   The students most likely have which type of rock?   Coal ⊝   Peridotite ⊝   Dolomite ⊝   Sandstone ⊝ CLEAR ALL

A general chemistry student found a chunk of metal in the basement of a friend's house. To figure out what it was, she used the ideas just developed in class about density. First she measured the mass of the metal to be 198.1 grams. Then she dropped the metal into a measuring cup and found that it displaced 17.3 mL of water. Calculate the density of the metal.

A rectangular lead apron is placed over the chest of a patient while X-rays are being taken in a dental office. The apron measures 75.0cm by 50.0cm by 0.20cm. If the density of the lead is 11.3g/cm^3, what is the mass (in g) of the lead apron?

A student weighed their penny (mass = 2.499 g) and followed the same experimental procedure you did in the lab. They found that the penny contained 0.0980 g of copper, or, 3.92%. Estimate the thickness of the copper coating with the following formula. From the US Mint website: the diameter of a penny is 19.05 mm and the thickness is 1.52 mm. The density of copper is 8.96 g/cm3. TIP: your final answer will have the units of cm (think about what to do first.). mass of Cu volume density of Cu Thickness of Cu Coating = area (diameter 2 T T (diameter) (thickness) O 7.39 x 104 cm O 1.65 x 103 cm O 4.22 x 102 cm O 2.80 x 103 cm O 1.89 x 105 cm O impossible to determine

(1)   A rectangular block of wood has the following dimensions: 10.0 cm x 5.00 cm x 4.00 cm. The block weight 100 g. What is the density of the block of wood? (2)  What is the mass of a 400-mL sample of ethyl alcohol if its density is 0.8 g/mL?

Assume the density of air at room temperature is 1.2 g/mL. A student is holding two balloons filled with gases: one balloon filled with hydrogen gas ( density=0.082 g/mL) and second balloon filled with carbondioxide gas (density=1.9 g/mL). predict what would happen if the student release both the balloons?

A Part A Planet X rotates in the same manner as the earth, around an axis through its north and south poles, and is perfectly spherical. An astronaut who weighs 943.0 N on the earth weighs 910.0 N at the north pole of Planet X and only 850.0 N at its equator.

The volume of a gold idol is approximately 1.0L. The density of gold is 19.3 g/ml and the density of sand is 2.3 g/ml. What volume would the bag of sand be in order to weigh exactly the same as the idol?

Backpackers often use canisters of white gas to fuel a cooking stove’s burner. If one canister contains 2.05 L of white gas, and the density of the gas is 0.700 g/cm3 , how many kilograms of fuel are in one canister?
