the weight of naphthalene in your samole could be determined
2个回答
Weighing by difference is more accurate.Because there will be naphthalene sticking on the samole while being transferred to the evaporating dish.Weighing by difference can include the portion that sticks on the samole,but directly weighing the amount of solid collected on the evaporating dish will be less than the actual amount because it does not inlcude the naphthalene sticking on the samole.Therefore,weighing by difference will have less error and more accuracy.
