Which of the following is NOT true about constant weighing in the experiment? Constant weight is achieved when two consecutive measured weights agree within plus or minus 0.3 mg. It involves a cycle of heating, cooling, and weighing. A proportionality constant will be multiplied to the measured weight to account for loss of water. A desiccator is used to avoid moisture to be absorbed by the sample.
