Among the official methods for determining moisture content, the Volumetric Method is commonly employed. It involves utilizing a graduated cylinder to measure the volume of water displaced by a known mass of the substance being tested.

Procedure:

• A sample of known mass is carefully weighed.
• The sample is placed in a graduated cylinder partially filled with water.
• The volume of water displaced is measured and recorded.
• The moisture content is calculated using the following formula:
  Moisture Content (%) = (Initial Volume – Final Volume) / Mass of Sample x 100%

Advantages:

• Relatively simple and straightforward procedure.
• Does not require complex equipment or specialized expertise.
• Can be applied to various sample sizes and forms.

Limitations:

• Accuracy may be affected by the precision of the graduated cylinder and the ability to accurately measure the displaced water volume.
• Assumes that all of the displaced water is due to the moisture content of the sample, which may not always be the case.

Conclusion:

The Volumetric Method offers a practical and accessible approach to determining the moisture content of a substance. While it has advantages in terms of simplicity and versatility, its limitations should be carefully considered to ensure accurate and reliable results.
