FeCl3 + NH4OH ---> Fe(OH)3 + NH4Cl Sally and Jo are conducting an experiment where they add 3grams of
FeCl3 and 2grams of NH4OH. Both of them did the experiment, but Sally
did it in a sealed bag and Jo did it in an open beaker. Sally's final mass was
6grams and Jo's final mass was 4 grams. Who did the experiment
correctly?

what is the question because that is not a question.

that tool is called an altimeter which measures your altitude which can be used to tell which atmosphere you are currently in, including the stratosphere.
