Questions for Exercise 1.4 Qi. A chemist gathers aliquots of water, methanol and acetic acid; measures the volume and the mass of each aliquot; and then pours the three aliquots together to form a mixture. The chemist then measures the mass and volume of the newly formed mixture. Finally, they calculate the amount of molecules brought into the mixture by each component as well as the total amount of molecules in the mixture. These results are summarized in the table below: Amount Mass Volume (Moles) (g) (mL) Before Mixing water 0.110 2.00 2.00 methanol 0.062 2.00 2.53 acetic acid 0.017 1.00 1.05 Totals Mixture 0.19 5.00 5.40 After Mixing (solution) (a) Based on the chemist's results, determine the relative abundance of acetic acid as a: mass fraction, mole fraction, volume fraction, volume concentration, mass concentration, molarity, and molality Note 1: (The tear sheet from the previous exercise (RO) provides definitions that may be helpful.) Note 2: Help for the molality calculation: Generally the solvent is the most abundant liquid. However in this problem water has more moles, and methanol has a bigger volume. Thus in calculating molality you need to choose the solvent. You can select water, methanol or water + methanol as your solvent. Because the calculated molality will change depending upon what you chose as the solvent, please state your solvent choice along with your answer.
