Marathon 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 the at the temperature of the gold bar and the liquid are 86ºC. If the density of the liquid decreases by 1.0% for each 10ºC rise in temperature(over the range 0ºC to 50ºC) determine

a. the density of the gold at 86ºC

b. the density of the liquid at 40ºC

Note: Parts a and b can be answered separately.
