You have an irregularly shaped piece of an unknown metal. To identify it, you determine its density and then compare this value with known values that you look up in the chemistry library. The mass of the metal is 74.122 g. Because of the irregular shape, you measure the volume by submerging the metal in water in a graduated cylinder. When you do this, the water level in the cylinder rises from 28.2 mL to 36.7 mL. (a) What is the density of the metal? (Use the correct number of significant figures in your answer.) (b) The unknown is one of the seven metals listed below. Isis possible to identify the metal based on the density you have calculated? Explain.

Container A and Container B were filled completely with chicken powder. The total mass of 1/3 of the chicken powder in Container B and 1/11 of the chicken powder in Container A was 570 g. If 5/11 of the chicken powder in Container A was poured out, the total mass of the chicken powder in both containers became 2.28 kg. How much chicken powder was in
(a) Container A in grams?
(b) Container B in grams?
A chemist prepares a solution of silver(I) nitrate AgNO3 by measuring out 6.4102 x 10^2 μmol of silver(I) nitrate into a 450.mL volumetric flask and filling the flask to the mark with water. Calculate the concentration in mol/L of the chemist's silver(I) nitrate solution. Round your answer to 2 significant digits.
A metal object of an irregular shape has a mass of 31.5 grams. When the metal is added to
water in a graduated cylinder, the volume of water increases from 5.28 mL to 7.61 mL.
(A) How much water does the metal displace?
(B) Calculate the density of the metal.
(C) Is the metal made of platinum? Explain.
(Hint: the density of platinum = 21.4 g/cm³)
