A sample of vinegar is 7.00 mass % acetic acid (60.052 g/mol) in water. What is the mole fraction of acetic acid in the vinegar sample? What is the molality of the vinegar sample?
Describe the preparation of a mixture containing ethanol and water where Xethanol = 0.27 and Xwater = 0.73
Calculate the molality and mole fraction of an aqueous solution that is 12.5 % NaOH by mass.
Calculate the mole fraction of a solution prepared by dissolving 15.6 mL of ethanol (CH3CH2OH) in 250.00 mL of water at room temperature. Assume that the final volume is the sum of each component. The densities of ethanol and water are 0.789 g/mL and 1.00 g/mL, respectively.
