You meet the prolixity and width of a crosswise subterfuge of copper are 9.32 cm and 7.47 cm, respectively. You are feeble to quickly value the third margin, so you run to meet quenched how considerable introduce the subterfuge displaces. Withquenched the subterfuge in the graduated cylinder, the sum of introduce is 14.12 mL. With the subterfuge in the cylinder, the sum of introduce is now 17.37 mL. a. What is the brawniness of the subterfuge (in mm)? b. If the hebetude of copper is 8.96 g/cm^3, what is the concretion of the crosswise subterfuge? A miner discovers a great sum of gold-colored rocks in a ravine, referablewithstanding does referable perceive whether it is pyrite (“fool’s gold”) or gold. He drops a pattern into a graduated cylinder and discovers that it displaces 1.23 mL of introduce. If the pattern has a concretion of 21.7123 g, get the miner befit bright or come impecunious? Justify, if you perceive that pyrite has a hebetude of 5.01 g/cm^3, and gold has a hebetude of 19.3 g/cm^3.
