A 0.500 mL sample of a liquid is found to weigh 7.96 g. Calculate the density of the liquid in units of g/cm^3 and g/mL. g/mL g/cm^3
An irregular piece of the metal is found to weigh 87.4g. It is then placed into a graduated cylinder that contains some liquid. The liquid in the cylinder has an initial volume of 18.46 ml. After the metal was added and the liquid's level rises to 24.14 mL afterward. What is the density of this piece of metal in g/mL units? Enter a number without units.
A solid aluminum cube is attached to spring-like device and is able to oscillate horizontally with negligible friction. Each side of the cube is 1.50 cm long. The cube is initially pulled to a point where it stretches the spring-like device by 2.55 cm where it is held at rest with a horizontal force of 1.35 N. What is the frequency at which it oscillates when it is released? (Assume the density of aluminum is 2.70 g/cm3.) answer in Hz
1) Aluminum has a density of 2.699 g/cm3, and the radius of the
aluminum atom is 143 pm. Verify that the metal crystallizes as a
face-centered cube.
EX. 3 Calculate the percentage of the total volume is occupied by spheres in (a) a simple cube, (b) a body-centered cube, and (c) a face-centered cube in which all atoms are identical. (b) A body-centered cube (bcc)
A cube of copper metal has a density of 8.96 g/cm3. The cube has a mass of 29.54 g. The atomic radius of a copper atom is 1.28 angstroms. How many atoms is the cube of copper metal?
A 15.00 g metal sphere was found to have a diameter of 1.85 cm. The volume of a sphere is V = (4/3)pir^3. Calculate the density of the sphere and assuming that the sphere is made out of one of the elements, aluminum, chromium, iron, lead, titanium or zinc, determine its composition. A 5581 gram irregular object made out of one of the metals in #6 raises the water level in a graduated cylinder from the 17.6 mL level to...
