1. Solve the following queries. Make sure you show full procedure using conversion factors if applicable a) Three solutions were produced: 50 g of C4H8O4 in 2 L water, 50 g of C8H1407 in 2 L water, and 50 g of C12H20O10 in 2 L solution. What are the molalities of these solutions? b) A sucrose solution was prepared by dissolving 13.5 g C12H22O11 in sufficient water to make exactly 100 mL, which was then found to have a density of 1.050 g/mL. Compute the molar concentration and the molality of the solution. c) What is the volume of concentrated H₂SO4 (density 1.835 g/cm³, 93.2% H₂SO4 by weight) required to make up 500mL of 3.00N acid solution.
