In the movie Goldfinger, James Bond foils a plot
to break into Fort Knox. 007 does some quick mental
calculations to determine the feasibility of removing the
gold. If the price of gold is $14.00 per troy ounce (31.1035
grams) at the time the movie was produced, what is the
mass (in kg) of 1 million dollars of gold? What is the
volume of 1 million dollars of gold in L. How much would

The following experiment is performed with an unknown
liquid. The liquid is added to a graduated cylinder with
a mass of 54.6789 grams. After 20.00 mL of the liquid is
added to the cylinder (at 298 K), the mass is 74.6215
grams. Is the liquid water? How do you know? If it is not
water, what could it be?
The experiment is repeated with a second liquid, after 21.3
mL of this liquid (at 20 °C) is added the mass of the
cylinder is 72.7364 grams. Is the second liquid ethanol?
How do you know? If it is not ethanol, what could it be?
