The water displacement method is a set of measurements used to calculate the volume of an irregularly shaped object. These objects are commonly known as irregularly shaped solids.
<h3>What is water displacement method ?</h3>
The displacement method (also known as the submersion or dunking method) can be used to accurately measure the volume of the human body and other irregularly shaped objects by measuring the volume of fluid displaced when the object is submerged.
Place your jewelry on a table or in your hand, and pour some white vinegar directly on the metal (a dropper can also be used). If the metal of the jewelry changes color, it is not pure gold; if it continues to shine, you have real gold in your hand.
Thus, The water displacement method is a set of measurements used to calculate the volume of an irregularly shaped object.

Answer:
<span>Formula for sodium hydroxide is represented by <u>NaOH</u>.
Explanation:
The reaction of Sodium oxide with water is as follow,
Na</span>₂O + H₂O → 2 NaOH
<span>
Na</span>₂O is considered as a strong basic oxide as it contains O²⁻ which has high tendency to bind with hydrogen atoms. This reaction is an exothermic reaction and is conducted in cold water to produce NaOH.<span>
