Gold can be hammered into extremely thin sheets called gold leaf. A 200-mg piece of gold (density = 19.32 g/cm3) is hammered into a sheet measuring 2.4 ft x 1.0 ft. %3D What is the average thickness of the sheet in meters? Hints: Calculate the volume of the sheet from its density and mass, and then use the volume relationship for a rectangular solid, V = length x width x thickness.

The radius of cesium atom, Cs, 1s 265 pm, and its mass is 2.21 x 10 22 g. What is the density of the atom in grams per cubic centimeter (g/cm')? Assume the nucleus is a sphere with volume, V = 3. (1 pm = 1×10-12 m).
You have a mole of ping pong balls and want to ship them to a near-by town. You have packing boxes that measure 24 inches by 24 inches by 18 inches. How many boxes do you need to pack up all the ping pong balls? The radius of a ping pong ball is 20 mm. If you make any approximations or assumptions, please list them.
Suppose the absorbance of a 0.084 M solution of nickel(II) nitrate in water is measured to be 0.305 in a cuvette with a path length of 1.00 cm. If the solution is then diluted by a factor of 3, what do you expect the absorbance of the diluted solution to be, when measured in the same 1.00-cm cuvette? Round your answer to the correct number of significant figures
Calculate the length (in m) of a rectangular solid that weighs 95.5 g and has a width of 2.50 cm and thickness of 1.75 cm. The density of the solid is 3.15 g/cm3. I'm a little confused with setting up the formula.
The shattered glass case at the scene of a jewelry store robbery was determined to be made of potash borosilicate glass, which has a density of 2.162.16 g/mL. A 4.2124.212 g glass fragment was recovered from a suspect's clothing. When the fragment was placed into a graduated cylinder filled with water, 1.841.84 mL of the water was displaced. Calculate the density of the glass fragment.
The concentration of carbon monoxide (CO), a common air pollutant, is found in a room to be 5.7 x 10-3 mg/cm3. How many grams of CO are present in the room if the room's dimensions measure 3.5m x 3.0m x 3.2m?

Calculate the edge length in m and the volume in L for a cubical box that will “exactly” contain 4.32x1023 atoms. Assume the diameter of the Argon atom is 3.4 Å (1.000 Å = 1.000x10-10 m). Assume the atoms touch each other so that the closest distance between atomic centers (nuclei) is 3.4 Å and the atoms fill the box with MANY layers of Argon atoms.Note: a cubical box needs only one measurement to be defined because each edge of a cube is exactly the same length, l,so that the volume of the box, V = l3.
In the opening scene of the movie Raiders of the Lost Ark, Indiana Jones tries to remove a gold idol from a booby-trapped pedestal. He replaces a gold (D = 19.32 g/cm²³) idol of dimensions 5.0 inches by 5.0 inches by 5.0 inches with a bag of sand of approximately double the volume with sand (D = 3.65 g/cm³). Is the bag of sand really equal to the gold idol or will Dr. Jones set off the trap? Explain your answer and include a mathematical explanation. ML Cm3
