Webconstant weight and measuring the soil sample mass after and before drying. The water mass (or weight) is the difference between the weights of the wet and oven dry samples. The criterion for a dry soil sample is the soil sample that has been dried to constant weight in oven at temperature between 100 – 110 oC (105 oC is typical). It WebDrying to constant mass The precipitate was recovered by filtration, washed and dried to constant mass and was found to have a mass of 0-63 g.
