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.

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 density of a proton is approximately 4.0 x 1014 g/cm³. If the mass of the proton is 1.7 x 10.24 g, calculate its volume. V-12 g 1.7x1024 4.0x10²4 вусть (4.25x 10-39 cm³ 4 b.

5. a) At what temperature is the temperature in degrees Fahrenheit equal to
twice the temperature in degrees Celsius?
b) The average daytime temperatures on earth and Jupiter are 72 °F and
313 K, respectively. Calculate the difference in temperature, in C.
between these two planets.
6. For a material to float on the surface of the water, the material must
have a density less than that of water (1.0 g/mL) and must not react with
the water or dissolve in it. A spherical ball has a radius of 0.50 cm and
weighs 2.0 g. Will this ball float or sink when placed in water? (Note:
Volume of a sphere r .)
7. a)Using examples, explain the difference between a physical property and
a chemical property. b) Do the following statements describe chemical or
physical properties?
(i) Oxygen gas supports combustion. (ii) Fertilizers help to increase
agricultural production. ii) Water boils below 100°C on top of a
mountain. (iv) Lead is denser than aluminum. (v) Uranium…
