Question
1. Precisely define weight percent, molarity, molality, and mole fraction. Be sure to specify units and component (total solution, solute, or solvent). 2. A solution is prepared by dissolving 4.00 g of NaOH in 250. g of water. Assume the resulting solution has a density of 1.00 g/mL. What is the a) weight % b) molarity of the solution? c) molality of the solution? d) mole fraction of water in the solution? 3. Calculate the molarity, molality and mole fraction of water in each of these solutions Solute Density weight mole fraction of dissolved of Molarity (M) molality (m) % water (XH20) in water solution 1.19 HCI 36.0% g/cm3 1.84 H2SO4 96.0% g/cm3
