1. (HARDEST EVER!) A cylindrical bar of gold that is 1.5 in high and .25 in diameter has a mass of 23.1984 g as determined on an analytical balance. An empty grad. cylinder is weighed on a triple beam balance and has 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 palced in the grad 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 86Degrees Farenheit. If the density of the liquid decreases by 1.0% for each 10 degress celcius rise in temperature (over the range 0 to 50 degrees celcius) determine….

a)the density of the gold at 86 degs. farenherit,

b)the density of the liquid at 40 degs. farenheit

Note: Parts a and b can be answered independently.
