Massing Out 120 Grams of Sodium Chloride
Massing out 120 grams of sodium chloride is a fundamental process in various scientific and industrial applications. It involves accurately measuring and transferring a specific amount of sodium chloride, commonly known as salt, for precise use.
Materials and Equipment
- Sodium chloride (NaCl)
- Analytical balance with a readability of 0.001 grams or better
- Weighing paper or boat
- Spatula
- Funnel
Procedure
- Calibrate the analytical balance according to the manufacturer’s instructions.
- Fold the weighing paper or boat into a suitable container for holding the sodium chloride.
- Place the weighing paper or boat on the balance and tare it to zero.
- Carefully add sodium chloride to the weighing paper or boat using a spatula.
- Record the weight of the sodium chloride to the nearest 0.001 grams.
- Transfer the weighed sodium chloride to the desired container using a funnel.
Safety Precautions, Massing out 120 grams of sodium chloride
- Wear gloves and safety glasses when handling sodium chloride to avoid skin and eye irritation.
- Do not ingest or inhale sodium chloride, as it can be harmful.
- Store sodium chloride in a dry and sealed container to prevent moisture absorption.
Applications
