4. A laboratory runs a solids test. The weight of the crucible = 48.6212 g. A 100 mL sample is placed in the crucible and the water is evaporated.The weight of the crucible and dry solids = 48.6432 g. The crucible is placed in a 600°C furnace for 24 hrs and cooled in a desiccator.The weight of the cooled crucible and residue, or unburned solids = 48.6300 g. Find the total, volatile and fixed solids.
