A 28.0 % by mass solution of Iodine(not Iodide)andCCl4 has a density of 1.56 g/mL.
Convert this mass percent into the followingconcentrationexpressions:
Since it doesn't state how much solutionyou have, assumeyou have 100 g ofsolution. Then a 28.0 % solution would contain28.0 g Iodine.

| ± Convert between Units of Concentration Chemists often use molarity M, in moles/liter, to measure the concentration of solutions. Molarity is a common unit of concentration because the volume of a liquid is very easy to measure. However, the drawback of using molarity is that volume is a temperature-dependent quantity. As temperature changes, density changes, which affects volume. Volume markings for most laboratory glassware are calibrated for room temperature, about 20âC.Fortunately, there are several other ways of expressing concentration that do not involve volume and are therefore temperature independent. | A 2.350Ã10â2M solution of NaCl in water is at 20.0âC. The sample was created by dissolving a sample of NaCl in water and then bringing the volume up to 1.000 L. It was determined that the volume of water needed to do this was 999.4 mL . The density of water at 20.0âC is 0.9982 g/mL. Part A Calculate the molality of the salt solution. Express your answer to four significant figures and include the appropriate units.
