In an evaporation of water experiment, the initial mass of water in a beaker was 10.5775 +/- 0.0002 g. after some time, the mass of the water in the beaker was 10.3005 +/- 0.0002 g. the mass evaporated is calculated by subtracting the final mass from the initial mass. what is the final propagated error on the evaporated mass?
