Question

List three sources of error you expected to encounter in measuring molar mass of a volatil compound experiment and describe how this method is designed (or could be better designed) to minimize tge listed error sources?

Answer 1

The three possible error that might be encountered are:-

1) The air inside the flask should be completely swept out. Otherwise it will measured with the mass of volatile compound and molar mass may increase.

2) Temperature of the setup should be constant because if the temperature change volume of the gas will change .Hence error may occur in the calculation of molar mass.

3) Since the vapour of volatile compound is not ideal gas . So temperature  of unknown should not be much more the boiling point of substance. As the may cause deviation.
