Question: cantron Corpora 9 / 10 - 11 CA 12 A 3 A: CA CA A> 1234567 25. Consider 100 g of a 7.5% (mass) solution
cantron Corpora 9 / 10 - 11 CA 12 A 3 A: CA CA A> 1234567 25. Consider 100 g of a 7.5% (mass) solution of AICI,. (12 points total) a) Convert the concentration from 7.5% (mass) to... i) molarity; and ii) molality (8 points) First, complete the table below. Then calculate the corresponding molarity and molality of AICI,. Hint: if we have 100 g of a 7.5% (mass) solution of AlCl3, what is the mass of AICI? Show your work! (Partial credit is your friend. ^_^) Solvent (HO) (4 points) Mass (g) Moles AICI (formula unit, not particles!) Reference info Solute (AIC13) 92.59 56 ma 133.33 g/mol ,56m01 18.02 g/mol Solution 100 g malality - 56motes/ -18kg = 3.1= moral Density=1.00 g/mL mass 100g-7,5g = 92.5g 7.5gx (Imole of AIC 3/133.339) =.56mo) Molarity: (hint: what is the volume of the solution based on the density and mass?) (2 points)
