Marelb.pdf 20 "Parts-per" notation is commonly used in chemistry to describe small values of dimensionless quantities. For example, a mass fraction of 1 part per million (ppm) is equivalent to a 1 g of solute per million grams of solution (i.e. solute + solvent), or 1 mg of solute per kg of solution. A solution is made by dissolving 358.4 mg of iodine in 0.2500 L of ethanol (the density of ethanol is 0.7893 kg L-¹). What is the mass fraction of iodine in this solution, expressed in ppm? (a) 1130 ppm (b) 1132 ppm (c) 1434 ppm (d) 1813 ppm (e) 1816 ppm + 21/146 Type here to search Et W 2 35°C im Stichiometry + 158.09% 94E
