suppose the temperature in the room is several degrees warmer than the water in the water in the 1l beaker, and that the trapped gas (hydrogen and water vapor) warms up to the temperature of the room. if the data analysis is still done using the temperature of the water for the temperature of the trapped gas, will the calculated mass percent of metal in the sample be greater than, less than, or equal to real mass percent?
