Two substances with intermolecular forces of similar type and magnitude are likely to be soluble in each other. The saying "like dissolves like" will help you predict the solubility of a substance in a solvent. Discuss the importance of this saying.
A sample of a liquid hydrocarbon know to consist of molecules with five carbon atoms is vaporized in a .204 L flask by immersion in a water bath at 101?. The barometric pressure is 767 torr, and the remaining gas weighs .482 g. What is the molecul..
