You are given a "Gold Crown" to determine whether it is made of pure Gold or not. It has a mass of 675 grams when it is weighed in the air. Then it is submerged in oil (with density of 957 kg/m^3), it reads 640 grams. 7. Find the density of the Crown. Compare to the Gold density 19320 kg/m^3, is it really pure Gold?

Caffeine is a substance whose aroma can be detected by the human nose in the smallest amount. Thethreshold limit is 4.3 × 10^-11 grams per liter of air. If the current price of 25 g of caffeine is PhP 18.1,determine the cost (in PhP) to supply enough vanillin so that the aroma could be detected in a largeaircraft hangar with a volume of 3.0 × 10^8 ft^3.
You are supplied with another cylinder made of the same material. If the cylinder length is 1.83 feet, calculate the mass of this cylinder, in grams. Use the true density of the solid in this calculation, and assume that the cylinder diameter is the same as all the other cylinders you measured. Show your work. Calculate the mass of this cylinder, in grams. Length = 1.83 feet True density = 1.35 g/cm^3 Diameter = 1.55 cm

A general chemistry student found a chunk of metal in the basement of a friend’s house. To figure out what it was, she used the ideas just developed in class about density. She measured the mass of the metal to be 175.2 grams. Then she dropped the metal into a measuring cup and found that it displaced 15.3 mL of water. Calculate the density of the metal. What element is this metal most likely to be?
A chemist bought a small piece solid figurine suspected to be gold. Knowing that gold has a density of 19.3 g/cm^3, he chemist decides to determine its density. The figurine is put into a graduated cylinder that contains 32.6 mL of water. The reading with the figurine in the water is 45.2 mL. The mass of the figurine is 225.1g. Is the figurine made of pure gold? explain your reasoning.
