Clare extracted GONG, an essential oil. Clare utilized steam distillation to extract GONG from the plant's leaves. Clare discovered that the mixture boils at 98.5 degrees Celsius, with the vapor pressures of GONG and water being 5.06625 kPa and 725 mm Hg, respectively. Dee discovered that the distillation yielded 0.7249 mL of GONG and 1.2378 g of water. According to data, GONG has a density of 0.9789 g/mL. Determine GONG's molecular weight (in grams per mole).

Fatty acid mixtures can be used as drug release systems by taking advantage of the different thermal properties of the mixture when compared to those of the pure substances. A mixture of two fatty acids, myristic acid (MA) + stearic acid (SA), exhibits the following (experimentally determined) phase diagram. Sketch a cooling curve for 64% MA over the temperature range of 68 to 40 o Each time the slope of cooling curve changes, label the approximate temperature, as well as the components and phase (or phases) present in that region of the curve.
