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?

How many atoms of oxygen are contained in 160 grams of n2o3

How many grams of co(g) are there in 74.5 ml of the gas at 0.933 atm and 30o c?
