Halothane is one of the modern anesthetics which is nonflammable and relatively safe for patients. What is the molar mass of halothane if 456 milligrams is 52.8 milliliters at 22°C and 805 torr?

To find the molar mass, use the ideal gas law: PV = nRT. Convert 805 torr to atm (805/760), 52.8 mL to liters (0.0528 L), and 456 mg to grams (0.456 g). Solve for n (moles) and then divide the mass by moles to find the molar mass. The calculation gives approximately 197 g/mol.
