In chemistry,
normality is a measure of the concentration of a solution, defined as the number of moles of solute per liter of solution.
The formula for normality
N = (moles of solute) / (volume of solution in liters)
- Where N is the normality, and
- the numerator (moles of solute) represents the number of moles of solute in the solution, and
- the denominator (volume of solution in liters) represents the volume of the solution in liters.
In mathematics, a normal vector is a vector that is perpendicular to a given plane. The formula for a normal vector can be derived from the equation of the plane.
For example,
for a plane with equation ax + by + cz = d, the normal vector is given by:
<a, b, c>
- Where <a, b, c> is the normal vector, and
- a, b, and c are the coefficients in the equation of the plane.
The formula for normality depends on the specific definition being used.
