i. Calculate the relative molecular mass of anhydrous aluminium chloride vapour at each temperature. R=8.31J/K. ii. What is the probable molecular formula of aluminium chloride vapour at 200^circ c and

To calculate the relative molecular mass of anhydrous aluminium chloride vapor at a given temperature, we can use the ideal gas equation in the form of the molar mass equation: where:- is the molar mass,- is the density of the gas,- is the universal gas constant ( ),- is the temperature in Kelvin,- is the pressure.However, since the problem does not provide specific values for density or pressure, let's assume that you have these values from an experiment or another source to proceed with calculations.For the probable molecular formula of aluminum chloride vapor at :Aluminum chloride (AlCl₃) can exist as a dimer (Al₂Cl₆) in the vapor phase at certain temperatures. At higher temperatures, it tends to dissociate into monomers (AlCl₃).1. Convert the temperature from Celsius to Kelvin: 2. If experimental data shows that the calculated molar mass is approximately 267 g/mol, this suggests the presence of the dimer Al₂Cl₆ because: - The molar mass of AlCl₃ is approximately 133.5 g/mol. - The molar mass of Al₂Cl₆ is approximately 267 g/mol.Therefore, at , the probable molecular formula of aluminum chloride vapor is Al₂Cl₆.
