You are working in a lab in the Amazon rainforest looking for new plant-based drugs. You have isolated, purified, and crystallized a compound using a simple silica column, but need to determine its molecular weight. Of course there is no GC/MS where you are. Instead, you dissolve 1.647 g of the compound in 100.0 mL of water. You put this in a U-tube with a semi- permeable membrane in the middle, and add distilled water to the other side. At 300 K (it's warm in the jungle), the height of the solution rises by 0.61 m (p = 20 kg/m³). Calculate the molar mass of the compound and the freezing and boiling points of the solution. Assume that the solution behaves ideally.
