9. Engr. Tabor was given 0.6216 g of an unidentified solute. To identify the molecular weight of the said solute, he mixed 0.5216 g of naphthalene in 78.03 mL of carbon tetrachloride and measured its boiling point, which happened to be 77.122 deg C. He then mixed the unidentified solute in equal amounts of the solvent as that of the previous mixture. The boiling point of the second mixture was measured to be 77.367 deg C. What is the molecular weight of the unidentified solute?
You are a chemical developer for a major automotive parts supplier that develops antifreeze designed specifically for their vehicles. Antifreeze lowers the freezing point of water relative to pure water. This is an example of the colligative property of freezing point depression. In the presence of antifreeze, the freezing point of water – which serves as a coolant in internal combustion engines – will be lowered, thus preventing potentially catastrophic damage to the engine that would otherwise occur upon expansion of water due to freezing. Despite its name, anti-freeze also plays an important role in keeping your engine working during the summer months: the anti-freeze also acts to elevate the boiling point of the water so that it doesn’t start to boil on really hot days. Your boss is considering using a calcium chloride solution as anti-freeze and wants you to study the impact of the new anti-freeze on boiling. To be able to see a measurable effect, your boiling point elevation must…
A metal, M, of atomic mass 56 amu reacts with chlorine to form a salt that can be represented as MCly. A boiling point X• elevation experiment is performed to determine the subscript x, and therefore, the formula of the salt. A 34.6 g sample of the salt is dissolved in 100.0 g of water and the boiling point of the solution is found to be 377.34 K. Find the formula of the salt. Assume complete dissociation of the salt in solution. formula:
