A cylindrical bar of gold that is 1.5 in high and 0.25 in
Chapter , Problem 94(choose chapter or problem)
A cylindrical bar of gold that is 1.5 in high and 0.25 in in diameter has a mass of 23.1984 g, as determined on an analytical balance. An empty graduated cylinder is weighed on a triple-beam balance and has a mass of 73.47 g. After pouring a small amount of a liquid into the graduated cylinder, the mass is 79.16 g. When the gold cylinder is placed in the graduated cylinder (the liquid covers the top of the gold cylinder), the volume indicated on the graduated cylinder is 8.5 mL. Assume that the temperature of the gold bar and the liquid are 86°F. If the density of the liquid decreases by 1.0% for each 10.°C rise in temperature (over the range 0 to 50°C), determine
a. the density of the gold at 86°F.
b. the density of the liquid at 40.°F..

b. the density of the liquid at 40.°F..
ANSWER:
Step 1 of 3
Volume of the gold cylinder can be calculated by the following formula;
