You are given a "Gold Crown" to determine whether it is made of pure Gold or not. It has a mass of 67 grams when it is weighed in the air. Then it is submerged in oil (with density of 957 kg/m^3), it reads 6 grams 7. Find the density of the Crown. Compare to the Gold density 19320 kg/m^3, is it really pure Gold? A glass of iced tea contains a large chunk of pure ice partially floating on the iced tea. Given the density of ice as 917 kg/m^3, and density of iced tea as 1008 kg/m^2. 8 Find the percent volume of ice that is floating above the water level. 9. Convert 2.5 atm into Pascal, Ib/in^2, and kPa. 10. Seawater density is 1024 kg/m^3. A diver can only safely stand 5 atm when diving down. How deep can he go down?
