According to Dalton; All matter is made up of small particles called atoms.
This problem is providing us with the mass and density of a sample of liquid magnesium as 0.015 g and 1.738 g/cm³, respectively. Thus the volume, in microliters, of this same is required and found to be 8.63 μL according to the following calculations:
<h3>Density:</h3>
In science, density is defined as the degree of compactness of a substance and is calculated with:
Thus, given both the mass and density, we can solve for the volume as shown below:
By plugging in, we obtain the answer in cm³ first:
Then, we convert it to microliters as follows:

Explanation:
The Intermolecular force of attraction exists within the water molecule. This type of intermolecular force of attraction is known as a hydrogen bond. A hydrogen bond is a dipole-dipole intermolecular attraction that occurs when hydrogen is covalently bonded to highly electronegative elements of a small atomic size.
When the heat is applied to this intermolecular force, the heat disrupts the intermolecular force, and the surface tension is being broken. This is what caused a hot needle to sink when placed in cold water. But when a cold needle is placed on the surface of warm water, the cold needle will not break up the warm water's surface tension. As a result, the cold need sinks in the warm water.
