Question

**The density of a certain type of plastic is 0.83
g/cm**^{3}**. If a sheet of this plastic is
10.0 m long, 1.0 m wide, and 1 cm thick, what is its
mass?**

Answer #1

density = 0.83 g / cm^3

length = 10 m = 1000 cm

width = 1 m = 100 cm

thickness = 1 cm

volume = lenght x width x thickness

= 1000 x 100 x 1

= 100000 cm^3

mass = density x volume

= 0.83 x 100000

= 83000 g

**mass = 83000 g = 83 kg**

The density of osmium is reported to be 22,610 kg/m3. What is
the density in g/cm3? What is the mass of a block of osmium
measuring 10.0 cm x 8.0 cm x 9.0 cm? Please give the electronic
configuration and orbital diagram of osmium. Is this metal
paramagnetic or diamagnetic?

Gold has a density of 19.3 g/cm3, and quartz has a
density of 2.65 g/cm3. A sample of quartz contains gold.
If the quartz sample has a mass of 10 g and a volume of 3
cm3, what is the mass in grams of gold in the quartz
sample?

A positron emerges normally from a 4-mm-thick plastic slab
(density 1.14 g cm–3) with an energy of 1.62 MeV. What was its
energy when it entered the slab?

A solid cylinder of uniform density of 0.85 g/cm3
floats in a glass of water tinted light blue by food coloring.
Its circular surfaces are horizontal. What effect will the
following changes, each made to the initial system, have on
X, the height of the upper surface above the
water? The liquids added do not mix with the water, and the
cylinder never hits the bottom.
(No change, increase, decrease)
More tinted water is added to the glass.
The cylinder...

It is found that it takes a
2.36-cm-thick piece of Pd metal foil (density 12.0
g/cm3) to reduce the intensity of a beam of thermal
neutrons to exactly 10-3 of its original intensity.
Calculate the neutron capture cross section of Pd metal in units of
barns.

Assuming that water has a density of exactly 1 g/cm3, find the
mass of one cubic meter of water in kilograms. (b) Suppose that it
takes 10.0 h to drain a container of 5700 m3 of water. What is the
"mass flow rate," in kilograms per second, of water from the
container?

The sulfuric acid (98 g/mol) in a car battery has a density of
1.225 g/cm3 and is 3.75 M. What is the molality, mole fraction and
percentage of sulfuric acid by mass in this solution?

Gold, which has a density of 19.32 g/cm3, is the most
ductile metal and can be pressed into a thin leaf or drawn out into
a long fiber. (a) If a sample of gold with a mass
of 3.245 g, is pressed into a leaf of 3.989 ?m thickness, what is
the area of the leaf? (b) If, instead, the gold is
drawn out into a cylindrical fiber of radius 2.700 ?m, what is the
length of the fiber?

A fish initially has the same density as the sea water around
it: 1.026 g/cm3. Using its air bladder, the fish increases its
volume by 5% with a negligible change in its mass. What is the
fish's resulting acceleration? Group of answer choices
0.33 m/s2
0.88 m/s2
0.27 m/s2
0.49 m/s2
0.16 m/s2

Ten
grams of plastic beads with a density of 1.2 g/cm^3 are added to
500 mL of an organic solvent with a density of 0.8 g/cm^3. What is
the concentration of the plastic beads in mg/L? (This is a curve
ball!)
