Since the density of a substances varies with pressure and temperature we need a reference point for comparing the densities of different substances. The reference point we choose is somewhat arbitrary and changes from region to region but is typically atmospheric pressure (14.7 psig or 101325 Paa) and "normal" temperature (15 deg C or 60 deg F). The density measured at these reference conditions is the reference (or base) density.

The conversion from milligrams (mg) to milliliters (ml) in this case is based on the density of the liquid medication. Without knowing the density, it's not possible to give an accurate answer. You would need to know the density of the liquid in order to calculate the volume in milliliters needed to deliver 10 mg of medication.
As the depth of the fluid increases, the pressure increases. To explain this mathematicaly you consider the Sg of the fluid times the height of the column multiplied by gravity will give you the pressure at the base of the column

The base word for "explanation" is "explain".
Water is used as the base reference, and it has a value of 1. Anything less dense than water is expressed in numbers smaller than 1 (.71) for example. Anything denser than water is expressed in numbers greater than 1 (2.7).
As temperature increases, base oil density typically decreases. This is due to the thermal expansion of the oil molecules, causing them to spread out and occupy a larger volume, resulting in lower density. Conversely, as temperature decreases, base oil density tends to increase.
The density of a solution at which the DNA feels no net force during centrifugation is called its bouyant density. This is the density in the density gradient where that particular DNA molecule will form a band as it stops going up or down.

Pressure is defined as the force acting per unit area. Force is the weight of the liquid. Weight = mass of the liquid x acceleration due to gravity Mass is got by the product of the volume and density. Volume is the product of the base area and height of the liquid. So pressure = area x hieght of the liquid x density x acceleration due to gravity / area As area gets cancelled, pressure = h d g So pressure depends only on the height of the liquid level or depth of the liquid. Hence independent of the shape. So the famous sayings: Water would find its own level.
To neutralize a liquid, you can add an acid to a base or a base to an acid in a controlled manner until the liquid reaches a pH of 7 (neutral). This reaction cancels out the effects of both the acid and base, resulting in a neutral solution.
An instrument used to measure the Specific Gravity (or Relative Density) of a liquid is called as a Hydrometer. It is the Ratio of the density of the liquid to the desnity of the fresh water (i.e. 1.000). The instrument consist of a glass chamber with Lead Shots or Mercury filled at the bottom or the base, to make it float upright.
