experiment stepzzz Flashcards
when measuring the rmm of a volatile liquid what items do we label?
rubber band , aluminium foil with pin hole , hotplate , thermometer , boiling water , volatile liquid vapour
first procedure in measuring the rmm of a volatile liquid
find the mass of our apparatus using a laboratory balance
second procedure in measuring the rmm of a volatile liquid
pouring approximately 10cm3 of our volatile liquid into the conical flask E.g. propanone or cyclohexane
3rd procedure in measuring the rmm of a volatile liquid.
we place our aluminum foil over the mouth of the conical flask making a small pinhole in the aluminum
4th procedure in measuring the rmm of a volatile liquid?
we clamp the flask into a large beaker of boiling water until all of our liquid has vaporised
5th procedure in measuring the rmm of a volatile liquid?
we measure the temperature of the boiling water aswell as the atmospheric pressure
