Final answer:
To find the molar mass of chloroform given the gas's conditions, use the Ideal Gas Law and convert known values such as temperature to Kelvin and pressure to atm as required.
Step-by-step explanation:
The question refers to collecting sulfur hexafluoride gas at a certain temperature and pressure and involves using the gas laws to determine the molar mass of chloroform from given conditions. To calculate the molar mass of chloroform, you can use the Ideal Gas Law, which is PV = nRT, where P is pressure, V is volume, n is the number of moles, R is the ideal gas constant, and T is temperature in Kelvin. In this situation, we know the weight of the chloroform, the volume of the flask, the pressure, and the temperature. Using the mass and the number of moles, you can find the molar mass (molar mass = mass / moles).
First, convert the temperature to Kelvin by adding 273.15 to the Celsius temperature. Convert pressure from mm Hg to atm if necessary (1 atm = 760 mm Hg), and use the mass of chloroform to find the moles using the Ideal Gas Law. From there, you'll be able to calculate the molar mass.
